Computer hangs when trying to start Software Center

  • 772

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

AND

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

EDIT

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...

  1. there is a all time default solution which I am following if I saw any thing like that .

    open your terminal sudo rm -rf /var/lib/apt/lists/*

    paste the above line . try again .

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

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F24AEA9FB05498B7
sudo apt-get update

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