How to upgrade to Linux Mint 17 Qiana

1. Check your Linux Mint version by running the following commands in Terminal.

$ sudo cat /etc/issue
$ sudo cat /etc/issue.net  
$ sudo cat /etc/lsb-release
$ sudo cat /etc/os-release

2. Make sure you create a backup copy of your system sources.

$ sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
$ sudo cp /etc/apt/sources.list.d/official-package-repositories.list /etc/apt/sources.list.d/official-package-repositories.list.bak

3.  Edit Linux Mint software list in ‘/etc/apt/sources.list.d/official-package-repositories.list‘ file:

sudo nano /etc/apt/sources.list.d/official-package-repositories.list

Replace “petra” with “qiana” and “saucy” with “trusty” on all lines. Save and exit.

4. Start the upgrade process this way:

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

5. Reboot, and repeat step 1 to verify that you have Mint 17 succesfully installed.
