Sorry, Ubuntu 16.04 has experienced an internal error

I just upgraded to 16.04 from 14.04 and I keep getting this error everytime I reboot my machine. How to resolve this issue? Is this a missing package issue?

Thanks

Solution 1:

I don't know if this is related to your problem, but it look very similar. Take a look at comment 7 in the below link for a possible work around.

There is a workaround to this problem that worked for me. From the terminal execute the following:

sudo apt --reinstall install signon-ui
sudo apt --reinstall install signon-ui-x11
sudo apt --reinstall install signon-ui-service
sudo reboot
