A little GUI made in bash + zenity, to bakup packages

If zenity isn't installed you can do :

 sudo apt install zenity 

This script ignores missing packages (if you got a newer version of your distributions for example), so some packages can be missing in the end. Launch the script within a terminal to see the debug outpout.

Also, if you're stuck in a loop try :

 sudo dpkg --configure -a 

Sometimes dpkg can be locked because of an error, and when it happens softwares can't be installed. This command is a way to resolve this problem.

Dependencies : zenity, bash, echo, grep, dpkg, awk, xargs
