When I type in the terminal:
sudo apt-get install "NAME OF THE PROGRAM"
there isn't any problem, but when I do:
sudo add-apt-repository ppa:"SMTHG HERE"
sudo apt-get update
sudo apt-get install "NAME OF THE PROGRAM"
I get the output:
E:Unable to locate package "NAME OF THE PROGRAM"
This has happened every time I try to install an application from a ppa.
Output of uname -a: Linux dcalderon-MS-7693 3.19.0-73-generic #81-Ubuntu SMP Tue Oct 18 16:03:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Specific example:
sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak
How should I proceed?
