I am using Ubuntu 18.04.2 LTS and, recently, every time I try to sudo apt-get upgrade the following occurs:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done

Setting up glibc (2.27-1) ...
chown: invalid user: ‘builder:builder’

dpkg: error processing package glibc (--configure):
 installed glibc package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 glibc
E: Sub-process /usr/bin/dpkg returned an error code (1)

Even if I try to sudo apt autoremove the same problem occurs.

I tried to Google this problem but I couldn't manage to solve it.

Does anyone have any idea how to fix this?

Thank you in advance.

When I run dpkg -l libc6 I get:

Desired=Unknown/Install/Remove/Purge/Hold

And when I do apt policy libc6 I get:

libc6:

  Version table:

        100 /var/lib/dpkg/status

The output for apt-cache policy glibc is:

glibc:
  Installed: 2.27-1
  Candidate: 2.27-1
  Version table:
 *** 2.27-1 100
        100 /var/lib/dpkg/status

  • Is this some kind of containerized (docker?) system?

  • hi @steeldriver No, it's not a docker system.

  • OK then sorry I have no idea why it would be trying to chown things to a builder:builder user/group. I hope someone else can think of something.

  • ... just one other thought, can you edit your question to include the output of dpkg -l libc6 and apt policy libc6 please

  • Of course! I just added what you asked

Thanks to @fkraiem, I finally solved the problem by simply removing glibc.

As @fkraiem said in the comments above, the package glibc does not officially exist in Ubuntu. I might have installed it, even though I don't remember when. So, it's most likely that I don't need it and should remove it.

After removing it everything seems fine and working normally again.
