When I try to install a package manager program, I get the following error:
Do I have to put in console something here? if so what do you have to get?An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: ' Error: Opening the cache (E: Type '30016' is not known on line 1 in source list /etc/apt/sources.list.d/karmic-partner.list, E:The list of sources could not be read.)'This usually means that your installed packages have unmet dependencies
thanks for any help.
