Eric Lambart, did you close the app by right clicking on the launcher icon and choosing "Exit" from the menu, before trying to launch it?
To find the app, you have two options: 1. or write "software update" (without the final "r") in the dash (Super key OR Super+A, not Super-R). 2. choose "System details" (I dont know the exact translation, but should be the first menu item) from the "gear" menu in the top right corner. Then click the button in bottom right corner, if updates are available. About the crashes, it's off topic for this bug, so please report it as a separate bug report. However, since I had similar problems, I can say you that it's probably a problem with the video drivers. Here's a couple of references that helped me to solve them: http://askubuntu.com/a/507299/11223 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1329689 -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Similarly if I do Super-S or Super-W it doesn't show up anywhere. Even if I alt-tab to the application nothing shows up. This happens only when update manager runs on its own. If I kill it and then launch it myself it comes to the foreground just fine. I'm not 100% sure whether this is a unity, compiz, or update-manager bug but so far my bet is on unity. =====Original Report===== Bug #877444 is showing again in latest updates, please re-open it.
