Just ran a regular software update, nothing abnormal. Prompted me to reboot, so I did, and once logged in the program ubuntu-software "crashed" (window opened briefly, then disappeared).

Rebooted a few time just to make sure this wasn't a glitch, and tried to run it from the terminal to see the error message:

$ ubuntu-software

Don't know how they are related (usually use apt install manually), but the program software-center seems to work fine, on the other hand. Annoying thing though is that double-clicking .deb packages seems to call ubuntu-software; trying to do so opens a window with package description and button "Install" (as usual), but clicking on the button kills the window. Can still install manually with dpkg -i, but would be good to know why this happens and how to fix it.

  • Could you please include the output of `sudo apt-get install -f` in your question? It might also be worth to [verify the integrity of all installed packages](/a/57728/175814) to check if Ubuntu Software and its dependency packages aren't corrupted. – David Foerster Jan 13 '17 at 18:18

You appear to have been affected by this bug in gdm3 You may wish to subscribe to it so that you get notified when it's repaired.

To confirm, issue the command cat /etc/X11/default-display-manager which should output the full path of your display manager. You might go so far as to change display managers as a workaround. This should get you a bit farther, hopefully this and a reboot will solve the too many open files problem as well..

As discussed here;

sudo apt-get upgrade gnome-software

This resolved this issue for me.
