I'm using Ubuntu 16.04.1 LTS. I need to install pgAdminIII from ubuntu software-center but the software-center doesn't open this morning. What should I do to fix this?
Try to reinstall the software center
sudo apt-get install --reinstall software-center
or if you're running Gnome
sudo add-apt-repository ppa:ubuntu-desktop/gnome-software sudo apt-get update sudo apt-get install --reinstall gnome-software packagekit
If it's still now working then type
And update your question with output
