How To Properly Upgrade Linux Mint 17.2 RC, Linux Mint 17.1 Or Linux Mint 17 To Linux Mint 17.2 Rafaela

Despite the fact that the MATE and Cinnamon flavors of Linux Mint 17.2 have been made available for download a few days ago, they have been officially released and announced on the Linux Mint blog yesterday.

Also, the developers have announced that Linux Mint 17.2 will be supported until 2019, being a LTS release.

Like Linux Mint 17 and Linux Mint 17.1, Linux Mint 17.2 Rafaela is based on Ubuntu 14.04 Trusty Tahr and uses latest generation desktop environments: Cinnamon 2.6 and MATE 1.10, but other Linux Mint-specific improvements have been implemented also.

Linux Mint 17.2 also brings updates for the Login Screen, Language Settings and Software Sources, new Artwork, system improvements, better UEFI support and enhanced experience for NVIDIA and Optimus GPU cards.

For specific information about each of the two flavors, see the MATE and Cinnamon announcements.

The official announcement:

“Linux Mint 17.2 is a long term support release which will be supported until 2019. It comes with updated software and brings refinements and many new features to make your desktop even more comfortable to use. A huge amount of work was done to review the CPU usage in various parts of Cinnamon, and many improvements were made. Performance was gained by optimizing how Cinnamon reacts to particular events and reducing the number of tasks or repeated tasks it performance,”

Upgrade instructions:

How to upgrade from Linux Mint 17.2 RC to Linux Mint 17.2 Rafaela (stable):

Because both the RC and the final version of Linux Mint 17.2 use the same repositories, you just need to perform a regular system upgrade:

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

How to upgrade from Linux Mint 17.1 Rebecca to Linux Mint 17.2 Rafaela:

First, backup to official sources, just in case, if something unexpected happens.

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

OR, if you are not familiar with wildcards, do:

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

Next, we have to replace qiana with rebecca, in the sources file. Instead of doing this by hand, taking the lines one by one, I will be using this sed oneliner:

$ sudo sed -i 's/rebecca/rafaela/g' /etc/apt/sources.list.d/official-package-repositories.list

Now, in order to finish the upgrade process, we have to update the local repository index and perform a regular system upgrade:

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

Revert the changes, only if the upgrade process does not finalize successfully:

Replace the modified sources list with the backup:

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

Upgrade the repository index and perform a system upgrade:

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