Right. https://bugs.launchpad.net/bugs/1799550 has been opened in 2018 to track the dual boot issue. This is the security issue I was referring to. Sorry for the confusion.

[Bug 1773457] Re: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems
The issue reported here is that /boot is not encrypted in the supported configurations. Which is meh - we don't have much authenticated encryption, so boot can still be manipulated. Sealed TPM measurements address the problem of verifying the bootloader, kernel, initrd, and the configuration better. It does not provide security by obfuscation as encryption does, but that obfuscation can be circumvented - you can modify an encrypted boot partition and still get a working system - and authenticated encryption that would also authenticate the content is not stable yet. I cannot say much on the other issue raised in recent comments on dual boot setups not installing encrypted, but I fail to see how it's related to this bug report I do want to point out that with devices now being sold with BitLocker out of the box, that you do have to disable BitLocker first to even get the ability to install another OS, so I fail to see how that improves the situation for dual boot users who need encryption. But in any case adding comments to bugs that are unrelated to the bug is not really helpful, you end up with nobody knowing what people are talking about anymore. Hence my suggestion would be to open a new bug report against ubiquity describing the dual boot setup issues so that that can be tracked on its own and we don't have to discuss two bugs in one bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

No it is not a grub issue. It's an issue with the installer which does not provide this option anymore. Wishlist..kind of but I think it is much closer to a big security issue than to a wishlist.

This doesn't look like it'll ever be done. Based on past experience, I don't think that Canonical takes encryption seriously. So, I've thrown in the towel. Since buying a new computer, I haven't used dual-boot. Instead, I installed Ubuntu using its full-disk LUKS encryption. I run Windows in a VM (VirtualBox) inside Ubuntu, so that LUKS also protects it. It's a good solution provided that your hardware is powerful enough.

Any updates on this? This is really critical in my opinion. My user case: - I work in a large, 1st rank university. - Unfortunately, moronic administration decides that the default system is mac, or if specific programs needed Windows, for laptops (we have RedHat desktop PCs though). - However, our IT has a tradition of allowing people to drift their own laptops, and they used to say yes to letting us be roots and buying what we wanted to dual boot Windows / Ubuntu. We do need windows in my group, so the only option is dual boot Windows / Ubuntu. - Since the option to have encrypted Ubuntu at installation side by side with Windows in just one click has disappeared, we have had an epidemic of people techies enough to use Ubuntu, but not techies enough to understand / care about encryption etc, installing non-encrypted Ubuntu on the side of windows. IT has learnt about it, and was furious (this is a violation of the IT agreement we sign together with our work contract since it is a clear security breach), and has now forbidden people to install ubuntu / drift university laptops on their own. - This means that we more or less cannot use Ubuntu any more until the one click encryption side-by-side with windows is back, and IT gets cool again. Really annoying. People either need to buy a separate laptop, and / or stop having ubuntu and move to mac. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1773457] Re: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems
** Description changed: In today's world, especially with the likes of the EU's GDPR and the many security fails, Ubuntu installer needs to support full-system encryption out of the box. This means encrypting not only /home but also both root and /boot. The only parts of the system that wouldn't be encrypted are the EFI partition and the initial Grub bootloader, for obvious reasons. It should also not delete other installed systems unless explicitly requested. On top of this, the previous method of encrypting data (ecryptfs) is now considered buggy, and full-disk encryption is recommended as an alternative. Unfortunately, the current implementation of full-disk encryption wipes any existing OS such as Windows, making the implementation unusable for most users. Now, using LUKS and LVM, it is already possible to have full-disk encryption (strictly, full-partition encryption because it leaves any existing OS alone), while encrypting /boot. Reference: https://help.ubuntu.com/community/ManualFullSystemEncryption ... but with one major limitation: Grub is incorrectly changed after an update affecting the kernel or Grub, so that a manual Grub update is required each time this happens (this is fully covered in the linked instructions). If the incorrect Grub change is fixed, it should be (relatively) simple to support full-system encryption in the installer. Further information (2018-08-17): The NCSC recommends, "Use LUKS/dm-crypt to provide full volume encryption."

[Bug 1773457] Re: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems
My attempts to install 20.04 beta desktop or 18.04 LTS netinstall expert mode with full disk LUKS encryption failed. 1. Tried installing 20.04 Desktop ISO: - selected manual partitioning - created a single partition spanning the entire disk - created a volume for encryption on the partition (LUKS) - the LUKS was created, but there is no way to select the sda1_crypt volume as physical device for LVM. The option is absent from the list! So I go manually: - exit out of the installation - open a terminal, create the LVM VG and two LVs: root and swap - start the installer again, now the LVM volumes are displayed - select the root volume to be used as ext4 on / - select swap LV to be used as swap - proceed with installation normally, it finishes without errors. - on reboot, grub drops to rescue shell, unable to find the "lvm" root disk. Probably due to missing GRUB_ENABLE_CRYPTODISK=y in /etc/default/grub. 2. Tried the 18.04 LTS netinstall booted over PXE: - selected Advanced options, Expert Install - used manual partitioning to create the same "MBR->partition1->LUKS->LVM->LVs root and swap" layout as above. - installation proceeds fine until the "Install GRUB bootloader to the master boot record", where it errors: "grub-install /dev/sda failed". I try different combinations of grub options here, none work. So I'm unable to create a bootable system. I could probably make the 2nd way work if I switched to the console, found out why it errors, fixed it, and installed it manually. But that's not expected of a normal user! So now, in 2020, we have no way to install Ubuntu without unencrypted /boot. I have numerous machines that I either installed this way in the past, or manually copied over installations to hand-created LUKS and LVM, and with minor tweaks (chrooting into the copied system, adding GRUB_ENABLE_CRYPTODISK=y and tweaking fstab and crypttab) I can get them to boot fine. I can swear this used to work on 14.04 and before, so this is a regression! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've primarily used Ubuntu for more than a decade, and would much prefer to keep using it as my daily OS, but this is a blocker for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The issue remains the same with 19.10 (beta I tried yesterday). The 19.10 Kubuntu installer cannot install an encrypted kubuntu in dual boot with e.g. windows10. It is still possible to setup such an encrypted kubuntu but it requires to chroot after the installer has finished its job and to configure crypttab manually. It is far from being user friendly and it gives a bad first impression. ** Changed in: ubiquity (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Agreed. "Full-system encryption needs to be supported out-of-the-box" full system shall mean 'the Linux partitions' an not 'the full disk'. In 19.04 it is not possible to install an encrypted kubuntu in dual boot with windows10 without playing with the command line. It means that no users new to Linux can encrypt the its Ubuntu.

*** This bug is a duplicate of bug 1514120 *** https://bugs.launchpad.net/bugs/1514120 I would like to support this bug report from the perspective of a security oriented, pragmatic user, likely the kind of which there are plenty out there. Ubuntu's great success has been and will be based on how user friendly it is, and an overwhelming majority of the people who are looking at security just want their whole system encrypted. Also in dual boot scenarios. Windows for general purpose, Ubuntu for security relevant tasks such as banking or sensitive administration. A wide-spread usecase. Confronting them with exceptions such as an unencrypted /boot partition, disabling encryption in dual boot scenarios or any other unnecessary complications will just lower Ubuntu's acceptance in an increasingly security aware user world. Academic discussions about whether or not encryption has been designed for tamper resistance just misses the point. Fact is that it does increase it. Think of someone who breaches my Windows installation, and discovers the parallel Ubuntu installation. They either just see one big chunk of random data, or they see a clear-text /boot partition they can play with. This is one unnecessary attack vector, no matter how easy or hard it is to use. I do not remember a single argument in this whole history against /boot encryption that mentions a real disadvantage of the functionality. Yes, there may be alternatives. No, it does not make a system perfectly safe.

@Jonathan Polom (s0nic0nslaught) Thank you for the extra information. The full-system encryption linked in the OP solves the part about /boot being accessed, which is a good thing. That leaves only three parts to be solved. 1. The error with Grub, which has been reported: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1062623 2.

[Bug 1773457] Re: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems
I am with Paddy on this one. This isn't a "nice to have" feature but an essential feature that any operating system with even a sliver of hope of enterprise-wide adoption needs to support in the second decade of the 21st century. Windows has the benefit of fully supporting TPM based encryption and secure boot which so each item loaded at boot time has a cryptographic signature which is verified by the secure boot system. Modifications will result in an un-bootable system. Mac OS X has FileVault along with System Integrity Protection which similarly will make it very difficult to boot poisoned pieces of the operating system to extract bits of information that should be protected on disk by encryption. Ubuntu, at this point, does not offer a level of tamper- resistance similar to this without implementing unsupported modifications that (like this method) are not for ordinary users who just want to install something "that works." This is both deeply disappointing to a security and privacy minded individual like myself and it WILL prevent adoption of this system in areas where complete system encryption and built-in tamper resistance are non-negotiable requirements (defense, financial, legal, healthcare, and more -- most industries are very security conscious now). I'm blown away by the animosity shown by some that have commented on this thread who dismiss this issue has unnecessary because "encryption isn't supposed to be used to prevent modification of items on disk" or that "the bug isn't really against the named packages" or to "use the minimal installer" to do this. A leading operating system (which Ubuntu should be considered one at this point) in the 21st century needs to support an easy, out of the box way to ensure private information stays private. The proof of concept attack to which the "full disk" encryption method supported by the Ubiquity installer is vulnerable to is fairly straight- forward to implement. It does require physical access to a system but this requirement is generally met when the device is portable, aka a laptop. Please see the procedure described here to understand how initrd/initramfs poisoning works: https://twopointfouristan.wordpress.com/2011/04/17/pwning-past-whole- disk-encryption/ Considering the relatively simplicity of this attack, as well as the existence of a clear way to remove this vulnerability, I think this issue needs to be addressed both in terms of updating the full disk encryption method supported in the installer, along with fixing the grub2 package so the issue Paddy had to write a script to fix no longer exists. I'd also like to offer an alternative method which could/should be examined for more official support, and that is to truly support secure boot by using signed kernel and initrd images. This would require Ubuntu to build in a way to sign kernels and initrd files with the Microsoft key, or to create self-signed keys on each machine and install them into the EFI. I almost prefer this version because it it uses secure boot for what it is intended to do: ensure the files loaded at boot time have not been tampered with. Finally, I'd like to add that Ubiquity also needs to support doing encryption with a btrfs root, which currently will result in a non- bootable system if you manage to configure it as such. When using btrfs as root it would also be nice if it supported an encrypted root without the use of LVM since btrfs over LVM is kind of redundant. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: In today's world, especially with the likes of the EU's GDPR and the many security fails, Ubuntu installer needs to support full-system encryption out of the box. This means encrypting not only /home but also both root and /boot. The only parts of the system that wouldn't be encrypted are the EFI partition and the initial Grub bootloader, for obvious reasons. It should also not delete other installed systems unless explicitly requested. On top of this, the previous method of encrypting data (ecryptfs) is now considered buggy, and full-disk encryption is recommended as an alternative. Unfortunately, the current implementation of full-disk encryption wipes any existing OS such as Windows, making the implementation unusable for most users. Now, using LUKS and LVM, it is already possible to have full-disk encryption (strictly, full-partition encryption because it leaves any existing OS alone), while encrypting /boot.

@Dimitri Thanks for your comments. I understand where you are coming from. I do think, however, that as Ubuntu is intended (and was intended right from day 1) to be "for human beings", it would make hugely more sense to support full-system encryption from the installer. People don't want to be messing around with "install this, then install that, then fix this other thing" especially as it's neither documented nor supported by Canonical. That's just life. While technical people love messing around — it's their job, after all! — your average "human being" hates it. (I also dislike it; I put together the method simply because I needed it. I documented the process publicly because I know that there are many, many people like me who need it.) Also, I have never had good results from installing a desktop environment over an existing system, even something as simple as Lubuntu desktop over an Ubuntu installation. That, too, is just life. This request is something that Ubuntu should support. It's not a "nice to have" feature. In today's world, it's a a "got to have" feature, whether for business, government, professionals, salespeople, scientific research, and even personal use. (If I could program, I'd amend the installer myself to implement this — it is open source, after all). This is made even more urgent by the fact that Ubuntu 18.04 no longer supports encryption at all. Even the recommended workaround, fscrypt, is broken. I cannot understand the antagonism to this request — it's a proven method; it's not particularly difficult; it's easy enough to modify the existing installer to do this; it's significantly better than the existing options; it uses only proven technology; and it would prove hugely popular, helping to tip the balance to switch to Ubuntu in organisations that are currently uncertain. I know that I were an internal sysadmin, or a consultant to a professional (I used to be both, decades ago), up to version 16.04 I would have recommended Ubuntu every time without hesitation. But, from 18.04, I absolutely would not, because it's too problematic to install with encryption and then keep it reliably up to date. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If you want to preserve other OS and setup encrypted partitions by hand, you can do so, since forever using the mini.iso d-i installer, and install ubuntu-desktop task. yes unencrypted /boot is currently a limitation with grub, but you can use sicherboot package to boot UEFI based systems securely without /boot, as that ensure the bootloader, kernel, initramfs are all in the UEFI partition, signed and booted with secureboot. none of that is typical for a desktop installer, nor is easy to explain in the UI. And things like above is adequatly easy to setup using the mini.iso and additional packages.

@Phillip I believe that in the heat of the argument the key point was lost. In the enterprise world, the "desktop" method of "lets assume we can wipe all user data" and "lets assume this is a single-disk use case" simply do not add up. For me, the current model is simply unusable for 2 fundamental reasons: A) As a corporate policy /precedes GDPR, but I presume it is not unique/ the only partition except from mandatory encryption is the EFI partition. This is not up for discussion. There is NO WAY you will even be able to win this argument with the InfoSec Crowd. Because they are right. You need to assume *not only* scenarios of external attacker but also the user himself mis-using the /boot partition to exchange confidential data. And please do not go with the "then you are already compromised so you lost anyway" argument. The point is is defense-in-depth. With trusted boot you can actually ignore the EFI-the system will refuse to boot if the EFI is messed with. Etc. B) And this is even more critical, I have a powerfull workstation with several SSDs used as Virtualization host for a bunch of VMs under VMware workstation. I NEED to use custom partitioning to be able to create a custom LUKS volume and pass that volume directly to VMs to do their stuff - while staying fully encrypted on the HW level. In summary, for "Kid's computer", the current approach is fine. No question there. Bu then, for a Kid's computer, Win10 is fine too so is a Mac ... What this bug report is about is how to address PROFESSIONAL / ADVANCED use cases seemlessly. Right now, the solution prepared by Paddy is absolutely fine - and it is even fine if it is NOT included in Uniquity. But we should get the Grub bug fixed - bar the need for the "RefreshGrub" script, I found Paddy's solution infitintely more practical than being forced to use Red Hat (which supports a custom configuration just fine) or a Mac for that matter. I am marking this against Grub too - as maybe first step is to fix the Grub bug and once that is done, consider extenting this to Ubiquity for the next LTS cycle. ** Also affects: grub (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1773457] Re: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems
I have just discovered that home-folder encryption has been removed from Ubuntu because, it seems, it is considered buggy and under-maintained. Full-disk encryption is recommended as an alternative. Reference: https://www.linuxuprising.com/2018/04/how-to-encrypt-home-folder-in-ubuntu.html As you already know, full-disk encryption wipes any existing OS such as Windows. Therefore, this gives extra impetus to this bug report. Phillip, I posted the message on the board as you requested, but as there has been no reply, I consider this request to be fully valid. ** Description changed: In today's world, especially with the likes of the EU's GDPR and the many security fails, Ubuntu installer needs to support full-system encryption out of the box. This means encrypting not only /home but also both root and /boot. The only parts of the system that wouldn't be encrypted are the EFI partition and the initial Grub bootloader, for obvious reasons.

A usb stick plugged into the back of the computer isn't likely to be noticed. You can also open up the case and put something inside. Or for that matter, the stick only needs to be there to boot the computer once, then it can be removed and the computer even made to go to sleep and present fake boot screens if desired so that it looks like it is booting normally when the user returns and turns it on. Or you can very likely find a chunk of disk somewhere that you can compress to make room to squeeze the malware onto the hard disk. Or a more sophisticated attacker may plug in a PCIe card with malware on it, or compromise the Intel management engine and have full remote control of your computer over the network that is completely undetectable. > Please, if you wish to continue this conversation further, please start > something on the Ubuntu Forums and post the link here.

Phillip, I think that you need to take this discussion to somewhere like Ubuntu Forums. If we were to accept your argument, we would say that there is no point whatsoever in encrypting anything, and we should eliminate the current option to encrypt the home folder when installing Ubuntu. This approach violates, among others, the EU's GDPR. We do need to encrypt our computers, and encrypting absolutely everything to help prevent malware is the best possible way forward. Full-system encryption is possible (there is already a how-to for this), and it should be implemented as there is very little to do to make it available in the default installer.

Who cares *where* the malware is? Encryption doesn't stop someone from compromising the machine. You can boot the machine from a USB stick, then boot the hard disk in a virtual machine, let it look like it is running normally for you to come put your password in to decrypt the disk, and the malware on the USB stick ( or in the ESP ) can then capture your password and steal your data. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773457 Title: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1773457/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1773457] Re: Full-system encryption needs to be supported out-of-the-box including /boot and should not delete other installed systems
Yes, I know this, Philip, but unlike with the current setup (where you can add malware to root and the kernel), with this method, the only thing that they can change is the ESP (EFI System Partition), because everything else is fully encrypted in a single partition using LVM within LUKS. They can't add, modify or delete anything whatsoever anywhere else. Not root. Not the kernel. Not /boot. Not /home. Nothing. There's no access even to the file system. You can't even see what type of file system it is, e.g. ext4 or BTRFS. There's no access even to the partitioning. All you can see when you boot with your malware USB is two physical partitions: 1. The ESP. 2. A single partition filled with apparently random data with a LUKS header. Not even a file system. Not even the partitioning details. That's it. It's not like ecryptfs, where you can see (and modify) the files in root and /boot, and where you can see (and corrupt) the files in /home even though the file names and contents are encrypted. With LUKS, you can't see anything. At all. Literally everything is encrypted apart from the ESP. Everything. Seriously. The only way to add malware is to somehow mess with the ESP. It's a pretty tall order. I suppose that it could be done, theoretically, but I've yet to see anything along these lines being done. And, when booting from the hard drive (not the malware USB), once you are past the EFI stage, Grub (which is encrypted and therefore cannot be replaced with malware) takes over, thereafter moving into Linux, which is encrypted and therefore cannot be replaced with malware. I hope that you understand what I'm saying. As you can see, it is a robust system that puts both Windows and the existing Ubuntu method to shame. I can't comment on Mac, because I haven't worked with it in decades. So, can you see that I don't understand what you are getting at? I'm trying to understand your objection, but I am lost.
