Upgrade Linux Mint 15 to Linux Mint 16

Try LiveCD before update

Before making an update to new version it could be a good approach to download an ISO, to make a LiveCD and try that new distribution works in LiveCD mode well on your hardware.

If you already have installed Linux Mint 15 and want just to update your current installation to latest version do the following (but always backup any critical data even before proven update operations).

Replace distro codename in sources.list files raring => saucy and olivia => petra

$ sudo sed -i 's/raring/saucy/' /etc/apt/sources.list
$ sudo sed -i 's/olivia/petra/' /etc/apt/sources.list
$ sudo sed -i 's/raring/saucy/' /etc/apt/sources.list.d/official-package-repositories.list
$ sudo sed -i 's/olivia/petra/' /etc/apt/sources.list.d/official-package-repositories.list

These are 2 required files, but if you had installed some PPA or repos review them manually in /etc/apt/sources.list.d folder and do the same.

Then run update

$ sudo apt-get update && sudo apt-get dist-upgrade
$ sudo apt-get upgrade

It really works

As for me this update went smooth and after 1.5-2 hours I got fully working and updated system. Compared to Ubuntu, that I couldn't ever get updated correctly - it is a perfect result.

Fresh install

If this update works not really good for you - better to do fresh install Linux Mint download page
