I have a problem regarding updating my Lubuntu 12.04.
When I do a
sudo apt-get update
I get these errors at the bottom of the output
W: Failed to fetch http://ppa.launchpad.net/gnomenu-tea...source/Sources 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/gnomenu-tea...-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
I'm not sure what these are, and how to "rebuild" my repository-list with the correct adresses.
Also, I sometimes get error-messages of the same sort when I use the GUI updater.
Lastly, how do I check that I indeed have the latest version of OpenJDK?
sudo apt-get install openjdk-7-jre
tells me I have the latest version, but I'm not sure.
Any help would be greatly appreciated!=)
