Re: [Trisquel-users] Trisquel 6: updates break GRUB
With the -i option, the 'sed' command really modifies the file at input. Without it, it takes the content of the file as its input and write its output to the terminal. The input file is left unmodified. In the context above I meant editing the kernel line in GRUB and booting it (like ssdclickofdeath explained) when I wrote booting by hand.

And this password is an annoyance for most users; useful for close to nobody. We have one more example here. For reference, here is the last time I discussed that annoyance in this one-week-old message: https://trisquel.info/en/forum/new-user-root-password-problems#comment-61998
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Success! I used the comments of Magic Banana, ssdclickofdeath, and lembas. (I followed the procedure of ssdclickofdeath, because I thought that I understood it.) I greatly appreciate the assistance that all of you provided to me.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
You can find the GRUB username/password for your install in /etc/grub.d/01_PASSWORD
Re: [Trisquel-users] Trisquel 6: updates break GRUB
thanks ssdclickofdeath. When I entered the e option at the grub menu, it asked for a username and password. I typed in my Trisquel ID and password, to no effect. I guess Grub has its own user name and password. Regarding your from the kernal, I assume you mean that this is a certain part of the grub congiration file.

Re: [Trisquel-users] Trisquel 6: updates break GRUB
I tried it again today. The file displayed upon executing the sed command. I did not see any occurences of the string '--unrestricted'. This time, I did not execute the command update-grub. Instead, I tried to execute the command umount /dev/sda1. Bash rejected this command, but I did not make a note of the reason why. I did a Ctrl-D, and then rebooted without the live-cd. No change in the boot-up.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
I was able to get it working by removing the --unrestricted parameter from the kernel on the top of the grub edit boot screen (press E to access it,) then booting from that kernel. Run sudo apt-get update; sudo apt-get upgrade then run update-grub. That worked for me.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Thanks Magic Banana. I entered all five of the commands you listed above. They all seemed to execute OK. What command(s) do I enter in order to get back to my live CD, and then reboot my PC (to see if it is actually fixed? Thanks.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Hello Magic Banana. I appreciate your assistance. First I altered the BIOS to boot first from the CD/DVD drive. (I made the default first boot media the 2nd boot media.) Here is what I tried tonight, from a terminal window in Trisquel 6 live cd (try trisquel option): trisquel@trisquel:~$ sudo chroot chroot: missing operand Try `chroot --help' for more information. trisquel@trisquel:~$ sudo mount /dev/sda1 /mnt trisquel@trisquel:~$ sudo gedit ./boot/grub/grub.cfg This opened up a grub file that was empty, so I closed the Gedit window. (gedit:4279): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.400LRX': No such file or directory (gedit:4279): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory (gedit:4279): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.EYZZRX': No such file or directory (gedit:4279): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory trisquel@trisquel:~$ trisquel@trisquel:~$ sudo chroot /dev/sda1 chroot: cannot change root directory to /dev/sda1: Not a directory At this point I quit.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Is sda1 really the root partition of the installed system (i.e., the partition mounted at /)? If yes, then that command was OK: $ sudo mount /dev/sda1 /mnt You can then execute the following command to mount the virtual filesystems (although I am not sure it is that essential): $ for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done Then, you can 'chroot' into the mounted root partition by specifying in argument the directory where it was mounted (not the device as you did): $ sudo chroot /mnt Now you can remove the '--unrestricted' parameters from /boot/grub/grub.cfg (as quidam told): $ sed 's/--unrestricted//g' /boot/grub/grub.cfg You could do that with a normal text editor (you seem to like GEdit) as well... but 'sed' is more geeky! :-) Finally: $ update-grub
Re: [Trisquel-users] Trisquel 6: updates break GRUB
I fixed my problem by using chroot from a live CD and making an upgrade of my system followed by update-grub.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
I would appreciate it if we could get an official set of detailed instructions for fixing this problem. Instructions that someone with only a very limited amount of technical experience with text commands could understand and follow. and, the sooner, the better. Thanks. Using a Trisquel 6 Live Cd, I tried sec's three text commands with sda1. I got Can't find and does not exist. For sda, I got a wierd hangup while loading a file inside gedit that I ended by ending gedit. I also tried Sim's chroot tip, and got no results. I have a ThinkPenguin Pro with only Trisquel 6 pre-installed. (I had substantial expertise with DOS commands many years ago.)
Re: [Trisquel-users] Trisquel 6: updates break GRUB
I forgot to run a software upgrade after booting, that's why it didn't work. I feel so stupid. :P
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Since the last update of my Trisquel 6 distribution, I get the following error message at the beginning of the booting process (quite after I select the linux version in the grub menu): error: symbol not found: 'grub_efi_secure_boot'. I couldn't find any '--unrestricted' parameter in grub.cfg What can I do to fix this problem? I didn't expect that something like this could happen due to a 'normal' update.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
During the recent grub updates on Trisquel 6 the installer asked if I wanted to change some config file as my differed from what was in the package and I asked to see the diff, however that was never shown. The next time I rebooted I was shown the grub menu unlike before.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Also you should be able to do it from grub itself, with the edit option, as long as you know the grub password. If you don't you can read it with a similar procedure, using a live cd mount / and read ./boot/grub/grub.cfg (but if you are already doing that you could as well remove the '--unrestricted' parameters).
Re: [Trisquel-users] Trisquel 6: updates break GRUB
With a live cd, mount your / partition and edit ./boot/grub/grub.cfg to remove the '--unrestricted' parameters. Then you should be able to reboot and update grub. Excuse the inconvenience.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Works for me. (perhaps your CD is corrupted) Once my LiveCD loaded, I used these commands: sudo mount /dev/sda5 /mnt[my / partition is on sda5, yours may differ] gksudo gedit /mnt/boot/grub/grub.cfg and i use find and replace to delete all the instaces of --unrestricted. happy new year
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Hi sec, i don't have partitions trisquel is my main os,i'll try to get another of trisquel and try out.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
No idea how to do that, my livecd doesn't load.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
This fix is overwritten when grub's settings are changed. I removed all instances of --unrestricted as you suggested, though without a live CD. When I restarted my computer, the correct kernel version showed up and booted properly. I later decided to change the grub splash image by modifying the /etc/default/grub file. After running update-grub and restarting, the same problem occurred. The top of the file you suggested to modify does state that it shouldn't be changed. /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub Are you aware of a more permanent solution?
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Fixed in version 1.99-21ubuntu3.17+6.0.1trisquel5
[Trisquel-users] Trisquel 6: updates break GRUB
After installing updates to trisquel 6, GRUB will no longer load Trisquel 6. Previous Linux versions (i.e. previous kernels) still show up as options, but when selected, an error appears citing the --unrestricted parameter. I have this exact same problem on 2 different machines, so should be easy to replicate. (but I can provide extra info on request, of course) I am triple-booting trisquel6, trisquel7 and windows. GRUB still loads T7 and Windows ok. It's just T6 that won't load.
Re: [Trisquel-users] Trisquel 6: updates break GRUB
Report it as a bug. See the item “issues” at the navigation bar that appears to the right and include all relevant information (Exact error message, and attach the file “/boot/grub/grub.cfg”.

Re: [Trisquel-users] Trisquel 6: updates break GRUB
Te same for me here. After instaling updates give me the error: Unknow argument --unrestricted
