After upgrading to Ubuntu 16.04, I cannot update my system. After the usual:

apt-get upgrade

I get this error:

Any ideas on how to fix this? apt-get clean and apt-get -f install did nothing.

Here the reason seemed to be a corrupted /var/cache/ldconfig/aux-cache.

The solution was to do (as root):

rm /var/cache/ldconfig/aux-cache

And afterwards execute

  • This worked for me, although he second command did not exist for me.

If it is in WSL, try (tks lifesaver.codes)

sudo mv /var/lib/dpkg/info/libc-bin.* /tmp/

sudo dpkg --remove --force-remove-reinstreq libc-bin

sudo dpkg --purge libc-bin

sudo apt install libc-bin

sudo mv /tmp/libc-bin.* /var/lib/dpkg/info/
  • This fixed the issue for me.

I used to have the same error here, I did the following command:

 sudo apt-get --reinstall install libc-bin

And it worked, it reinstalled the libc-bin package and solved the issue.

Hope it helps

I had this problem, it turned out to be limits related. This resolved it:

limit datasize 2000M

I had to run sudo rm /var/cache/ldconfig/aux-cache and sudo /sbin/ldconfig.real on WSL Ubuntu 20.04 .


With rm aux-cache i got
