How to add ppa repositories?
What are PPAs and how do I use them?
I always like to have my programs up to date but in ubuntu software center the software aren't always up to date. I know about repositorys and i'd like to add some so how can i find the repository of certain programs in launchpad. I'm using Ubuntu 12.04.1.
You can add a PPA location with the command
sudo add-apt-repository ppa:<ppa_name>
sudo add-apt-repository ppa:gnome-desktop
You can find some help on Ubuntu Documentation
Although there is no real 'root' user on Ubuntu, you have to have superuser permissions to add a PPA. On a regular system you have to do it with sudo: sudo add-apt-repository ...
And if you're sure the PPA name is typed correctly, you can add ' -y' to the end to auto-allow the new PPA. (sudo add-apt-repository ppa:gnome-desktop -y). This makes it easier to use post-installation scripts that add multiple PPAs without user intervention.
@puk Never tried it, but considering UbuntuForums it gives you a warning "W: Duplicate sources.list entry"
@puk : I know this post is old but I tried it. It did not coplained and added a duplicate line in my list of software sources. I tried it with: `sudo add-apt-repository ppa:freefilesync/ffs` ..... It reported zero error, correct keyring (priv and pub) creation,etc... Exited normally. At the end I was left with a repeated line: http://ppa.launchedpad.net/freefilesync/ffs/ubuntu trusty main (Source Code)
