Gah - it just gets worse : root@rsu-test:/# apt-get install build-essential Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation:
The following packages have unmet dependencies. build-essential: Depends: libc6-dev but it is not going to be installedor libc-dev Depends: g++ (>= 4:4.1.1) but it is not going to be installed E: Broken packages
which to choose ?
Difficult to say... This is not a Koha-specific issue anymore. You have to figure out what's wrong with your Ubuntu installation. You need to be able to compile C program and need so some packages. Make some searches on Ubuntu forums. Good luck. -- Frédéric
