How to upgrade to Linux Mint 18 from Linux Mint 17

It’s always exciting to upgrade to a newly polished Linux distro and hopefully there is an happy ending after upgrade. Linux Mint 18 is now available and that leaves us with two options including an upgrade option or a clean installation. While the latter is preferred method for junk less, and trouble free experience, it is not free from the backup of data headaches and re-installation of all the third-party programs you have been using all these days. Therefore, upgrade is most suited for most individuals. In this article, my focus is only on how to effectively upgrade to Linux Mint 18 from Linux Mint 17. This is 100% fully tested set of working instructions.

Upgrade to Linux Mint 17.3

Before doing anything else, I recommend upgrading your Linux Mint 17 to latest stable version 17.3. You can use Update Manager or the command prompt as shown below:

Update Manager: Make sure to install all the required updates and that it shows your system is up-to-date.

Update Manager - Linux Mint

Terminal: Alternatively you can update Linux Mint 17 using apt command:

Launch terminal and run the following commands one at a time followed by enter.

sudo apt update
sudo apt dist-upgrade

Enable Unlimited Terminal Scrolling

It is a good practice to enable unlimited scrolling so that you know what commands you have input previous time. By default settings, Linux Mint’s terminal stores only 512 lines of command lines which is too low especially when dealing with upgrades. So let’s bump it up to unlimited scrolling.

Open Terminal > Edit > Preferences > Scrolling. Then select “Unlimited“.

Install Mint Upgrade Tool

Next step is to install the Linux Mint Upgrade tool using apt command:

sudo apt install mintupgrade

You may have to input ‘Y’ during the process.

Simulate Upgrade before going Live

This step is not mandatory, but recommended. Like any simulations which are helpful in knowing the upcoming disasters or issues, this simple check command is quite useful.
