setup vagrant Ubuntu 12.04 LTS
when built-in vagrant and built-in virtualbox are outdated -
And we must use system ruby but its version is 1.8 and outdated -
sudo apt-get install ruby1.9.3 sudo apt-get autoremove sudo apt-get remove ruby1.8
upgrade virtualbox & vagrant
sudo apt-get remove virtualbox sudo apt-get remove vagrant
and do not install them from Ubuntu Software Center, download from website most recent version of them.
sudo dpkg -i vagrant_1.6.5_x86_64.deb sudo dpkg -i virtualbox-4.3_4.3.20-96996-Ubuntu-precise_i386.debdpkg
and then, follow regular guides and
vagrant up and
vagrant provision as needed.
