Ubuntu Apps Directory

E: Sub-process /usr/bin/dpkg returned an error code (1)

Asked by Munequita

hallo,

I've been using ubuntu 16.4. Sorry I don't know how to describe exactly this issue, but every time I try to install something I receive this on Synaptic Package

E: linux-image-extra-4.4.0-21-generic: subprocess installed post-removal script returned error exit status 1
E: linux-image-4.4.0-21-generic: subprocess installed post-removal script returned error exit status 1

On terminal trying to upgrade, I think it provides more details and repeat the same thing by the end:

hallo,

I hate computers, but anyway I've found the solution:

sudo su

rm /var/lib/dpkg/info/*

Deleting all files in /var/lib/dpkg/info/ was not a good idea.
Correct functioning of the package management system depends on the information stored in the files in that directory.

This action probably has broken your package management system.

If you now try the commands

sudo apt-get update
sudo apt-get dist-upgrade

you will receive hundreds of error messages about missing file in that directory.

No.

At least, it didn't happen to me.

As soon as I typed those commands I Updated and I didn't receive any error message. Maybe these commands are not for everyone, but you can try

sudo su

rm /var/lib/dpkg/info/*

Everything is Ok, I was unable to download and upgrade , my files, system.

Now I can update and download and finally I had a happy end.

What is the full output of the commands

sudo apt-get update
sudo apt-get dist-upgrade

when executed in a terminal window?
