How do I fix a download issue when updating?
I downloaded Ubuntu 12.04 and installed it in a VMware workstation. and I've been using all the installation commands:
sudo apt-get install automake
sudo apt-get install libboost-all-dev
and some others, but it kept on saying:
E: unable to locate package automake
E: unable to locate package libboost-all-dev
what could be the problem?
