I just installed Ubuntu 13.04 (coming from 11.04) today. And I can't use the Software Center from the Dash. When I start it from the dash, it always says that I don't have enough permissions to install software. But my user is in the sudo adm and lpadmin group, as it should be. The only way I can use it is with: "sudo software-center" in the console. Why doesn't it just ask for my password like it always did? Whats is the problem here?

If, by mistake, you have something like in /usr/share/polkit-1/actions/org.debian.apt.policy file:

...



  <action id="org.debian.apt.install-or-remove-packages">

    <description gettext-domain="aptdaemon">Install or remove packages</description>

    <message gettext-domain="aptdaemon">To install or remove software, you need to authenticate.</message>

    <defaults>

      <allow_any>no</allow_any>

      <allow_inactive>no</allow_inactive>

      <allow_active>no</allow_active>

    </defaults>

  </action>



...

you will get the following warning when you try to install something from Ubuntu Software Center:

You can check also the details from the warning.

So, check /usr/share/polkit-1/actions/org.debian.apt.policy file and be sure that is looking like this:

To edit it, switch to the root user in terminal with:

sudo -i

then run the following command:

gedit /usr/share/polkit-1/actions/org.debian.apt.policy

and close that root session with CTRLD or by typing exit.
