Ubuntu 18.04: Missing Problem Reporting option in Privacy Settings

Solution 1:

Try to sanitize apt cache.

sudo apt update && sudo apt-get check && sudo apt autoclean && sudo apt autoremove

Then try to purge and reinstall fixing broken and missing packages.

sudo apt update && sudo apt purge -y gnome-control-center && sudo apt install -y --install-recommends --fix-broken --fix-missing gnome-control-center

Solution 2:

How this would have happened or methods to reproduce the problem.

  • Add Pop!_OS repository using:

    sudo add-apt-repository ppa:system76/pop
    
  • Upgrade the system or upgrade/reinstall gnome-control-center. Use:

    sudo apt upgrade
    

    or

    sudo apt install gnome-control-center
    

What happened?

In my understanding the unofficial derivatives of Ubuntu like Pop!_OS remove options of bug reporting because they don't want their users to report bugs in Pop!_OS directly to Canonical (this is quite obvious since Canonical is not responsible for fixing their bugs) and they might haven't created the bug reporting mechanism for themselves (at least via their distribution)(if they have I don't know since I don't use Pop!_OS).

So, after adding repository of Pop!_OS, Ubuntu thinks the added repository has an updated version of gnome-control-center, that's why when upgraded, it uses Pop!_OS's repository, downloads and replaces the default version 1:3.28.2-0ubuntu0.18.04.2 with 1:3.28.2-0ubuntu0.18.04.2pop0 of gnome-control-center and install 2-3 more packages. Clearly the latter looks like a modified version and thus doesn't have Problem Reporting option under Privacy

What to do?

The only workaround I think is remove Pop!_OS's repository and reinstall gnome-control-center

sudo add-apt-repository --remove ppa:system76/pop
sudo apt autoremove gnome-control-center
sudo apt install gnome-control-center

Note: Don't use sudo apt install --reinstall gnome-control-center since I got an error like Reinstallation of gnome-control-center is not possible, it cannot be downloaded. Moreover packages installed via Pop!_OS's repository will be there even after removing repository unless explicitly removed. So don't worry about icons and themes, you can still use that.
