Every time I want to open Software Center to install something, my computer hangs before it starts. What could be the problem?


When I try sudo apt-get update and type my password, in the end of that I get error:

W: GPG error: precise InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F24AEA9FB05498B7


When I run software-center command from terminal, it does not give any errors, only thing it writes in output is:

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
2012-12-23 15:55:18,554 - - INFO - setting up proxy 'None'
2012-12-23 15:55:19,000 - softwarecenter.db.database - INFO - open() database: path=None use_axi=True use_agent=True

and after that it stays that way...

It looks like you have installed steam without importing the key. Run the following commands:

sudo apt-key adv --keyserver --recv-keys F24AEA9FB05498B7
sudo apt-get update

It will import the key for the steam repository. Now you can open the Software Center again.

Does Software Center give any errors when you run it by typing 'software-center' in a terminal? – Zilvador Dec 23 '12 at 10:21
I made edit, could you look at that please. – geoh Dec 23 '12 at 11:59
Hmm... try 'sudo apt-get --reinstall install software-center' – Zilvador Dec 23 '12 at 13:19
i reinstalled it, and now when i run it from terminal, computer still works, but nothing changes. it writes output in edit, and stays that way. :( – geoh Dec 23 '12 at 14:20
