I'm completely new to the Ubuntu world (I'm using Ubuntu 16.04). I encountered a very annoying problem when trying to install software. When I run
sudo apt-get application_name
nothing happens(installation freezes at 10% or whatever whatch here I'm just a beginner so i don't know how to fix it. In usc all the apps have disappeared(except the apps already installed). Just a suggestion:it might be a problem with my sources? Please help me to find and fix the issue.
