[SOLVED] linux-image-5.4.0-42-generic post-removal error

[zoli62]

During the apt-get upgrade, I get the following error message: installed linux-image-5.4.0-42-generic package post-removal script
subprocess returned error exit status 1
I have taken the usual steps for such cases. What to do?

Have you manually removed any kernels?

Have you manually removed any kernels?

I tried to remove the kernel in question manually, but without success.

O.K. Without knowing what you did as "the usual steps", have you tried

sudo apt autoremove

sudo apt autoclean

sudo apt clean

in that sequence?

Have you tried to remove that object in Synaptic or Muon?

And what is your dual boot configuration?

Yes, I ran the above commands in that order without any results. Anyway, the problem has been solved ever since. It turned out that I misconfigured something in grub.cfg with my grub menu timeout. After I fixed this, now everything is working normally. By the way, I don't use dual-boot, but multi-boot, because I have multiple systems installed on separate partitions in parallel.

Glad you got it solved.

You had the "Dual Boot" label on your original title, thus my question about dual boot. Multiboot is cool, too!

... I have multiple systems installed on separate partitions in parallel.

I used to juggle multiple systems in "multiple separate partitions"... then I moved to btrfs, with multiple systems in separate subvolumes, a huge time saver. Sometimes the installers won't do it directly, in which case I install to scratch partitions then move the system into the btrfs.

How much more stable is btrfs filesystem than ext4?
