I come to you in this moment of despair to beg for your mercyful aid:
How on Earth do I add a third party repo, including its public key? I have been searching a lot and haven't been able to do so
The repo I want to add is in this url: http://xbmc.org/wiki/?title=HOW-TO_inst ... ep-by-step
Since I have not been able to do this via synaptic, would you please advice on how to proceed? GUI indications or just command line instructions would suffice.
Mint beats Ubuntu in everythin, except on this
Thanks for your help
