Unable to turn on recommendations in Ubuntu Software Center

  • 772

When I start software-center from the terminal, I get the following output:

When I press the 'Turn on recommendations' button, I get the following:

Aborting.')}, signature=dbus.Signature('ss')) ()

I'm running Xubuntu 13.10. I think I accidentally removed a wrong package.

  1. Best Answer

    You need to install Ubuntu Single Sign-on:

    sudo apt-get install ubuntu-sso-client
sudo apt-get install ubuntu-sso-client-qt

  2. This actually works for me and I hope works for someone else where the answer does not work. I ran the software center from the terminal with admin privileges:

    sudo software-center

    Then press Turn Recommendations On, and instead of cancelling the process without any warning, the Ubuntu One log-in page pops out and I was able to log-in.

    Now, my question is, is there's any reason why the Software Center didn't have administrative privileges to execute the command? I remember I changed the password when the Heartbleed warning was sent out; It might caused this to happened, but there was no option to change credentials in the Software Center. I'm just assuming here.

    [UPDATE] - This only works for me once... when I try to do the same this is what I get:

        Traceback (most recent call last):

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

    Just FYI... can any body help on this? or should I post this same question again explaining that the answer posted here do not solve all problems with the log in? In my case is failing to log in returning problem receiving reply from remote application. So apparently is not in my end.

  3. I'd like to confirm that raphie's symptoms also occur in 15.04 amd64. I also see the "working" animation, but Software Recommendations fails to turn on or display any selections. Single-signon-client and single-signon-client-qt are also installed, and I am able to sign on to Ubuntu Forums. I reinstalled software-center but that didn't help either. Have performed system upgrades for several successive versions; I probably should do a fresh install next time.
