Hmm, in fact not only the "--interaction" argument is missing. This is not a serious patch, but the issue can be worked-around by adding the following lines after line 90 in /usr/lib/python3/dist- packages/sessioninstaller/gstinstaller.py:
parser.add_option("", "--interaction") parser.add_option("", "--desktop-id") parser.add_option("", "--startup-notification-id") After this monkey-patch, Totem shows me the dialog to install missing codecs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1499889 Title: gstreamer-codec-install: error: no such option: --interaction To manage notifications about this bug go to: https://bugs.launchpad.net/gst-plugins-base/+bug/1499889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
