can't install any apps

Question

I have Ubuntu 16.04 on my computer. In the last few days, I can't install any new apps from however I try to install it (.deb files, Software Center, dash). I can't even update the apps I installed before encountering this problem.

Can anybody help me?

Solution

Run the following commands:

rm ~/.local/share/gnome-software/*
sudo apt-get upgrade gnome-software
sudo apt-get update

This will solve the problem

Open a terminal by pressein Ctrl-Alt-T; run 'sudo apt update' and 'sudo apt upgrade' and update your question with the output of the two commands.
