Keine Berechtigungen für Software Center

Ich habe heute gerade Ubuntu 13.04 (ab 11.04) installiert. Und ich kann das Software Center vom Dash nicht verwenden. Wenn ich es vom Dash aus starte, heißt es immer, dass ich nicht genügend Berechtigungen habe, um Software zu installieren. Aber mein Benutzer ist in der Gruppe sudo adm und lpadmin, wie es sein sollte. Ich kann es nur verwenden mit: "sudo software-center" in der Konsole. Warum fragt es nicht einfach wie immer nach meinem Passwort? Was ist das Problem hier?

Wenn Sie versehentlich etwas in der /usr/share/polkit-1/actions/org.debian.apt.policyDatei haben:

...

  <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>

...

Sie erhalten die folgende Warnung, wenn Sie versuchen, etwas aus dem Ubuntu Software Center zu installieren:

Sie können auch die Details aus der Warnung überprüfen.

Überprüfen Sie also die /usr/share/polkit-1/actions/org.debian.apt.policyDatei und stellen Sie sicher, dass sie so aussieht:

Um es zu bearbeiten, wechseln Sie zum Root-Benutzer im Terminal mit:

sudo -i

Führen Sie dann den folgenden Befehl aus:

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

und schließen Sie diese Root-Sitzung mit CTRLDoder durch Eingabe exit.
