[SOLVED] Generic package post-installation script subprocess returned error exit status 1

[hedgehoggy]

The full error message is

Code: Select all

E: linux-image-5.4.0-89-generic: installed linux-image-5.4.0.89-generic package post-installation script subprocess returned error exit status 1

Everything on my system seems to be working for the moment, but what does this error mean and how do I fix it?

[sleeper12]

Try:

Code: Select all

 sudo apt autoremove 

Then see if the update works now.

Hi sleeper, thanks for your quick response. I did the autoremove and got this

Also, the updates I tried to install before didn't reappear in the update manager. I believe I got this type of error message with the new kernel, but also with some cinnamon updates that I was installing, carefully, one by one.

Ok, I'm not sure what's going on there. So, wait for better help.

[hedgehoggy]

Ok, no worries, thanks for trying!
I do have plenty of Timeshift snapshots to bounce back to, if that would help . . .

E: /usr/share/initramfs-tools/hooks/plymouth failed with return 1.

I don't even see how it's possible that that script "fails with return 1". Do you have the same checksum as me?

Code: Select all

$ crc32 /usr/share/initramfs-tools/hooks/plymouth

This is on 20.2 (Xfce). If not, does anything improve after sudo apt-get install --reinstall plymouth?

Over my head, but might this be a better command?:

Code: Select all

 sudo apt-get install --reinstall plymouth-* 

[rene]

Well, no, that would not be better. And, arr, crap, yes, it would have that issue; that reinstall triggers the very same postinst. And as far as I can quickly find you can't in fact skip that postinst either. Typically apt...

It was in any case not likely and especially given your equal CRC32. Err, arr, let me think...

[hedgehoggy]

Lot of output here, not sure if it's all relevant. Still appear to be getting error message:

What type of problem is this, exactly?

What type of problem is this, exactly?

Plymouth is the splash screen, and it fails to install onto the initramfs. But what type exactly...

It's going to be the set -e in /usr/share/initramfs-tools/hooks/plymouth that has the script exit after "something else" bugs out but unfortunately we don't get t see what said something else in fact is, making this hard to pin down non-locally.

Are you at all script-savvy? If I'd have had this issue I'd start instrumenting /usr/share/initramfs-tools/hooks/plymouth by e.g. putting "echo 1" (and 2,3,4, ...,so on) statements before every if, for and case statement to see where it fails.

My laptop just died, writing this on my phone

[rene]

Umm. Well, if something was segfaulting then that may have been the failure I suppose. It would not seem we, anyone, would be likely to be able to troubleshoot this from over the net though if now have a "dead" computer.

[hedgehoggy]

Ok, back now. I probably had way too many things open which is what caused the crash. I Timeshifted the hell out! Before doing so my laptop wouldn't start, and then when it did I got a weird looking grub boot screen. Anyway, this is my list of snapshots, if that helps . . .

Also here are the updates, before which I don't think I experienced any issues . . .

[rene]

And you still have a/the problem if you do e.g. sudo apt-get install -f?

[hedgehoggy]

Um, if I try that is it going to mess things up again?

[rene]

No, it'll only fix anything (known to apt to be) wrong.
