Starting Ubiquity in a kubuntu vivid live session just prints

and quits

nobody else has come across bug 1436497 that I'm aware of, can you think of anything you're doing different?

[Philip Muškovac (yofel)]

Doesn't look like I can reproduce this anymore either, maybe it was just an issue in that image

[Julien SCORDIA (julien-scordia)]

I have encountered the same error when trying to run Ubiquity in Kubuntu Vivid.
The workaround I found is to type /two times/:

$ sudo umount /run/udisks2/inhibit-polkit

Don't ask me why, but it solved the problem.

[Dale Trombley (buzzmandt)]

I have also encountered this and I can verify that Juliens workaround did indeed work
with only 1 exception, I needed only do the command one time. The second time it said it was already unmounted

$ sudo umount /run/udisks2/inhibit-polkit

Thank you

This happens with the regular Ubuntu too. Julien's workaround works for me too.
