I just updated to Ubuntu 12.10 but now LaTeX doesn't work any more. Kile always asks me "did you run LaTeX?". I'm quite new in this stuff, so it seems a bit strange for me, because in 12.04 it worked always without any exception. I also tried it with other Editors, but there were similar mistakes, so I guess it is related to the upgrade. Perhaps anybody of you has a hint.
There is a question at StackExchange with a error similar to what you get.
The solution stated there was to remove the
and check if the problem goes away. If not, you can rename the backup folder to its original name.
Upgrading has a drawback - programs may not work because of different structures and/or different, new or redundant libraries.
Solution : Try re-installing Kile(or any other program not working).
