I've have Ubuntu 15.04 on my laptop and just about everything I do requires me to enter my password.
What do I have to do so I don't have to keep entering my password?
To remove password prompts for commands/apps using sudo:
sudo adduser (your user name) sudo sudo visudo
%sudo ALL=(ALL:ALL) ALL
%sudo ALL=(ALL) NOPASSWD:ALL
visudo- Ctrl+x, y, Enter
sudo service sudo restart
To remove password prompts for some graphical applications that use policy kit, not sudo see https://askubuntu.com/a/614537/115816.
Done. Bad idea, but there.
