Unable to decrypt disk on boot

[CVirus]

Good day,

I enabled disk encryption when installing Ubuntu and it has been working flawlessly till kernel 5.8.0-45.51 was installed.

I keep getting this error when entering my password: "cryptsetup failed, bad password or options". I was somehow able to fall back into some shell while booting and it seems that any characters I type show up as diamonds "♦", except for the numbers. I also came across this thread which talks about a similar problem https://askubuntu.com/questions/1220022/keyboard-types-only-numbers-while-letters-are-typed-like-diamonds

Switching back to 5.8.0-44 fixes the issue for me.

I'm currently on Ubuntu 20.10
Would be happy to provide more details.

Thanks!

Hi

I am also having the same problem with Kernel 5.8.0-45.51.

The workaround posted above fixes it for me too.

Thanks

Status changed to 'Confirmed' because the bug affects multiple users.

To add to this, I have a password also set on grub which I can successfully enter before this problem occurs. Issue still exists in kernel 5.8.0-48

Thanks
