Any ideas?..

UPD:
Remove gnome-control-center with dependencies and install it again...
Nothing changed...

In my opinion there is a much better solution to that problem other than getting rid of a useful repository I personally like. What helped me is fixing the main repo priority. You may see that there are two repositories available for gnome-control-center package and the system76 is used now using a apt-cache policy gnome-control-center command:

gnome-control-center:
  Installed: 1:3.34.1-1ubuntu2pop1~1571679625~19.10~ef2ab1f
  Candidate: 1:3.34.1-1ubuntu2pop1~1571679625~19.10~ef2ab1f
  Version table:
 *** 1:3.34.1-1ubuntu2pop1~1571679625~19.10~ef2ab1f 500
        500 http://ppa.launchpad.net/system76/pop/ubuntu eoan/main amd64 Packages
        100 /var/lib/dpkg/status
     1:3.34.1-1ubuntu2 500
        500 http://de.archive.ubuntu.com/ubuntu eoan/main amd64 Packages

See those 500s? That's the default repo priority and it's the same. Let's give the main repo a higher priority (I'm on Ubuntu 19.10 codename eoan, please use your distro's codename instead):

    $ apt-cache policy | grep o=Ubuntu | grep c=main | grep a=eoan,
     release v=19.10,o=Ubuntu,a=eoan,n=eoan,l=Ubuntu,c=main,b=i386
     release v=19.10,o=Ubuntu,a=eoan,n=eoan,l=Ubuntu,c=main,b=amd64

That release ... part is kind of a filter you may use to give a repo different priority. Create and edit (as a root) a file called /etc/apt/preferences.d/main_repo_priority to look like this:

    Package: *
    Pin: release v=19.10,o=Ubuntu,a=eoan,n=eoan,l=Ubuntu,c=main,b=amd64
    Pin-Priority: 1001

And now finally reinstall the gnome-control-center:

    sudo apt install --reinstall gnome-control-center

And double check that the correct version is installed:

    $ apt-cache policy gnome-control-center
     gnome-control-center:
       Installed: 1:3.34.1-1ubuntu2
       Candidate: 1:3.34.1-1ubuntu2
       Version table:
          1:3.34.1-1ubuntu2pop1~1571679625~19.10~ef2ab1f 500
             500 http://ppa.launchpad.net/system76/pop/ubuntu eoan/main amd64                                                          Packages
     *** 1:3.34.1-1ubuntu2 1001
           1001 http://de.archive.ubuntu.com/ubuntu eoan/main amd64 Packages
            100 /var/lib/dpkg/status

I fix it.
I have third party repository ppa:system76/pop
It was added during pop-theme installation.
After update gnome-control-center from system76/pop replace original gnome-control-center.

What I've done:

  • remove pop-theme
  • remove system76/pop repository and GPG key from /etc/apt/*
  • remove apt cache
  • remove broken gnome-control-center from system76/pop
  • install original gnome-control-center

Now everything is working fine.
