I just ran a fresh installation of Ubuntu Mate 15.10 on my laptop and currently I need to install "build-essential". I ran:
sudo apt-get install build-essential
and got this error:
daniel@daniel-VGN-NR230FE:~$ sudo apt-get install build-essential

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.
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 installed or
libc-dev
Depends: g++ (>= 4:5.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I don't know if it has anything to do with this, but during the installation, I skipped some packages, since installing then would take forever (300 min or so).
Before doing the build-essential thing, I installed all the updates available via Software Updater and the incomplete language packs, but then again, got this error.
