Me too, Machine: Lenovo Think-book 14-IIL. Win 10 pre-installed. Since a couple of days I got permanently this error. Installing Ubuntu 20.04.1 anyway my machine became very unpredictable. Rebooting of either system (Win or Ubuntu) ended in a lot of error messages. I had to power off and then try to boot again. My work-around was: Install Ubuntu 18.04. This could be done without any problems. And then, I upgraded to Ubuntu 20.04.1 and so far as to today I finally got a stable system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888033 Title: Check error with 20.04-desktop ISO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1888033/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1888033] Re: Check error with 20.04-desktop ISO
Today I had the same exact problem. I found out that after creating on Windows 10 with win32diskimager an usb boot stick with Ubuntu 20.04, I had a called "writable" partition on that stick also. That efi image file you mentioned was the only file with a different md5sum. After that I created one more time a boot stick, but now on Ubuntu 18.04 with dd and now I had no issues anymore.

I have double-checked that there is nothing in the boot configuration that is configured to modify the contents of efi.img (which contains only the signed EFI executables - modification of which would cause the image to subsequently fail to boot). Any modification of this image must be coming from outside, which is not something we can account for. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888033 Title: Check error with 20.04-desktop ISO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1888033/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This certainly looks like a hardware dependent issue.

I have read you comment and I don't think excluding efi.img from the checks is a good idea. What if the modification is a sign of some advanced malware trying to hop from one computer to another? We certainly don't want to miss that! On the other hand, if some hardware platform wants to make the modification for legit reasons and in predictable ways, we can certainly allow that.

As explained in the thread, the issue is not with the files in the original iso but with the fact that the efi.img is modified during the boot process, making the subsequent checksum fail.

It might be helpful to take a closer look to see exactly what has changed.
