APT fails after fixing disk

[Sun_Blood]

Hi,

I just had some major corruptions on my /root partition that made it impossible to start the system. So I did a fsck on it from recovery and now the system starts like normal.

But there was apparently some files that could not be restored correctly(or have bin written to during corruption) and one of them is for apt so now I can't upgrade or reinstall package.

Any suggestions on how to fix this?

Try to run this:

run sudo dpkg --configure

later on you may try:

sudo apt-get install -f

or a combo:

sudo dpkg --configure -a --force-all

If it won't work you may have lost some data, files ,etc. which had held vital informations for apt-get. Try to rebuild them or something like that.
Sorry for spare solution, but I don't understand fully what has happen due to this coruption.

Sadly it didn't help. The problem is that the system think the package is installed and working correctly so it will not try to reinstall even with -f

I don't even understand if it is the apt-utils or libv4lconvert0:i386 that fails from reading the error message. And both packages is so embedded in the system so trying to remove them and reinstall seams impossible.

Sadly no errors.

Sounds like your apt-utils file list is corrupted or missing
Removing it, and reinstalling will regenerate it. (ignore errors in the first line, it is just to make sure there is no apt-utils list there already)

sudo mv /var/lib/dpkg/info/apt-utils.list /opt/apt-utils.list.backup
sudo apt-get update
sudo apt-get install --reinstall apt-utils

Try rebooting into the recovery kernal in the grub screen

run>>dpkg fix broken packages
follow prompts
if requested to run command manually it will probably be one of these:

  sudo dpkg --configure -a
                sudo apt-get install -f

resume normal boot
attempt what you are doing again

I think you are correct but it didn't work.
First of all I don't have the file /var/lib/dpkg/info/apt-utils.list so I could not move it. But I do have an md5 file, should I remove it?

And doing the reinstall gave me the same error

Do I need to be in recovery? Then I must move the computer(server) so I'll try it later.

hmm. Apt being fussy again I see.

Run

ls /var/cache/apt/archives/apt-utils*

If there is only one file,

Try

sudo dpkg -i --force all /var/cache/apt/archives/apt-utils*deb

Else, post the output.

Should work this time - I deleted mine to check.
