Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have used commands from tutorial site but it seems not to work. Why? I have just installed Ubuntu 10.04 yesterday and upgraded to to 11.10 today. Fresh install.

I am trying to type:

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa
sudo apt-get update
sudo apt-get install firefox-trunk

I also tried:

sudo add-apt-repository ppa:mozillateam/firefox-stable
sudo apt-get update && sudo apt-get upgrade

But I am getting:

XX@XX-PC:~$ sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa
