@Sebastien, you were right ! I have downgraded from proposed , several packages have been downgraded including the following
(maybe related on what you said) warning: downgrading gir1.2-packagekitglib-1.0 from 0.9.5-0ubuntu1 to 0.8.17-4ubuntu6~gcc5.2 Preparing to unpack .../gir1.2-packagekitglib-1.0_0.8.17-4ubuntu6~gcc5.2_amd64.deb ... Unpacking gir1.2-packagekitglib-1.0 (0.8.17-4ubuntu6~gcc5.2) over (0.9.5-0ubuntu1) ... dpkg: warning: downgrading libpackagekit-glib2-16:amd64 from 0.9.5-0ubuntu1 to 0.8.17-4ubuntu6~gcc5.2 Preparing to unpack .../libpackagekit-glib2-16_0.8.17-4ubuntu6~gcc5.2_amd64.deb .. Unpacking libpackagekit-glib2-16:amd64 (0.8.17-4ubuntu6~gcc5.2) over (0.9.5-0ubuntu1) and now the problem has been resolved. The system works OK, particularly and in general. I think I'll get off the 'proposed' train. Marking this bug as invalid ? (I guess). ** Tags removed: likely-dup -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500216 Title: Installing/Updating language support failed with "org.freedesktop.DBus.Error.NoReply" message To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/language-selector/+bug/1500216/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
