Well, I am unable to find the package for apt-get. Maybe it was removed? I would say it never existed except I find a number of websites telling me to search for it in Synaptic as well as apt-get only it is not there. Is there a place that I am not looking? A repository I need to add?
If not - I am going to need some help getting installed because unfortunately - I are n00b.
Hmm, I see you use ubuntu. I am not shure if the debian repository works correctly. The “GPG error” is not important.
If it`s not work, try to install ardour from source with scons. This is very easy. Scons reports all errors and missing dependence.
