I've recently updated my 14.10 installation to 15.04 (it went even smoother than I expected). After installation, running the Software Updater showed this:
Pressing "Partial Upgrade" asks for my password, shows the standard upgrade window, but then closes and this shows up:
If I click on "Continue", it simply tells me that "all software is up to date".
Can I do anything about this? Maybe it didn't fully install even though it claims it did? (I am also noticing screen tearing, which should've been fixed in the update, so that could be an indicator for that.)
