Every time 16.04 updates I must reinstall hplip. Is there a way to prevent this? I am using a HP Officejet Pro 8100. Today is the 3rd time it happened. I used both the repository and hp versions. Today I used the repository again.

Edit: 02/16/18:

The Ubuntu update problem that uninstalled unity and parts of desktop is now fixed.

Original answer

Something wonky is going on with Ubuntu updates. It breaks Unity and Ubuntu Desktop. To fix it you need aptitude which is not installed by default. Install aptitude by:

sudo apt install aptitude

If you fixed the problem by reinstalling unity by:

sudo aptitude install unity

Then there are a few things still broken including hplip. Use the command:

sudo aptitude install ubuntu-desktop

This installed hplip for me among other things.

If you have not reinstalled unity first, then you can just use the second command to fix both the problems. In that case, remember to say no to the first solution (do nothing) proposed by aptitude, and yes to the second solution.

See 2/15/18 compiz update broke unity

for details.

Hope this helps
