Code:
deb http://packages.linuxmint.com/ lisa main upstream import backport
deb http://archive.ubuntu.com/ubuntu/ oneiric main restricted universe multiverse

deb http://security.ubuntu.com/ubuntu/ oneiric-security main restricted universe multiverse
deb http://archive.canonical.com/ubuntu/ oneiric partner
deb http://packages.medibuntu.org/ oneiric free non-free
B.)
C.)
Code:
apt-get dist-upgrade
