computer freezes after update got stuck

Asked by Adria

Hello, I was running an Ubuntu update and suddenly it made the computer freeze. Cursor was not responding neither was any key combination command (AltF4 or Ctrl+Alt+Del for instance) to restart my laptop. I did then a hard reset, but the computer started on a terminal screen. I tried rebooting a few times, but I get the same situation.
Last screen I´ve been getting is as follows:

Can you try booting an older version of the kernel (from 'Advanced Option' in the grub menu)? Does this work, or fail the same way?

Hello @Manfred Hampl, thank you for the suggestion, I did and it worked. Now I will remove the broken version that was causing the problem, any idea of a command script for that? This newbie really appreciates you guys help!

Thank you!

To identify the broken and the functioning versions of the kernel, issue the following commands in a terminal window:

uname -a
lsb_release -crid
dpkg -l | grep ' linux-i'

and copy/paste all output onto this question document.
