[RESOLVED] Installation issue airtime 2.1.3 on Ubuntu 12.04 Server

Hello,

I run system Ubuntu Server 12.04 on a remote hosting server. I met an issue with Airtime installation, although I was following command line instructions from your EASY SET UP page. These are the informations and Error message that were displaiyed in my console after I sent this command line :

sudo software-center airtime-esay-setup.db

REPLY:

sudo software-center airtime-easy-setup.deb
Traceback (most recent call last):
File "/usr/bin/software-center", line 25, in
from gi.repository import Gtk, GObject
File "/usr/lib/python2.7/dist-packages/gi/importer.py", line 76, in load_module

raise RuntimeError("Gtk couldn't be initialized")
RuntimeError: Gtk couldn't be initialized

On Ubuntu forum, someone told me that software-center need a graphic interface, and that this is the reason why I shoub run UBUNTU DESKTOP iinstead of UBUNTU SERVER. But I do not agree this....

If informations in mentionned files have to be changed, or if some files must be moved to different folders, could you please guide me through this ?

If not, What means "RuntimeError" and what is Gtk ?
Can I skip this error and go ahead with the next command line (install airtime) ?

Please have in mind that I am new to Ubuntu.

Regards,
