When using sudo apt-get install libxerces27 libxerces27-dev libopenal0a libglut / libglut3-dev libfontcongfig1
It says for every package
E: Unable to locate package.
I am using precise distribution of linux 12.04
Please help.
Do these packages really exist? If these commands return no luck then your packages don't exist in Ubuntu's repositories or your PPAs. Try
sudo apt-get update
and try again. If that doesn't work then try
sudo apt-get install --fix-missing
and try again. If that does not work, then this means that your packages are not available in Ubuntu's repos or your PPAs.
