Have found this question multiple times on the forum, but none of the answers were serious enough. So the problem with ubuntu 12.04. LTS server is that after a fresh install you can not install build-essential package. This is what you get: Reading package lists... Building dependency tree... Reading state information... 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++ (>= 4:4.4.3) but it is not going to be installed

apt-get clean apt-get update apt-get -f install apt-get upgrade dpkg --configure -a apt-get autoclean apt-get --fix-missing install build-essential

uname -a gives: Linux sorrg01lin 3.11.0-15-generic #25~precise1-Ubuntu SMP Thu Jan 30 17:42:40 UTC 2014 i686 i686 i386 GNU/Linux
