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: http://repo.steampowered.com 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 - softwarecenter.ui.gtk3.app - 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...
