I am trying to install Coot on a laptop that runs Ubuntu. Following the instructions on the CCp4wiki http://strucbio.biologie.uni-konstanz.de/ccp4wiki/index.php/Coot#Packages_for_Ubuntu
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1DC81A57"Package coot is not available, but is referred to by another package.
sudo add-apt-repository ppa:mok0/ppa
apt-get update && apt-get install coot <- I had to add "sudo" to the beginning of this command and after the &&
and I received this fail message
