The Linux Mint project just opened today the upgrade path from Linux Mint 20 “Ulyana” to their newest release Linux Mint 20.1 “Ulyssa.”
Based on Ubuntu 20.04.1 LTS (Focal Fossa) and powered by Linux kernel 5.7 LTS, Linux Mint 20.1 “Ulyssa” was officially released on January 8th, 2021, bringing the latest Cinnamon 4.8 desktop environment, support for Web Apps, a new IPTV player app, printing, and scanning improvements, and many other changes.
But since Linux Mint 20.1 uses the same package base as Linux Mint 20, there’s no need to download the new ISO images to upgrade your existing installations. Instead, you just have to upgrade, which is an easy process for everyone using Linux Mint.
First and foremost, make sure you have a recent backup of your most precious files, just in case, something goes wrong (but it shouldn’t). Second, you’ll have to disable your screensaver, upgrade your Cinnamon spices, and update the mint update (5.7.3 or higher) and mint-upgrade-info (1.1.7 or higher) packages using the Update Manager.
Now you’re ready to upgrade your Linux Mint 20 installation to Linux Mint 20.1. All you have to do is fire up the System Upgrade utility, then go to the Edit menu and click on the Upgrade to “Linux Mint 20.1 Ulyssa” option.
The upgrade screen will pop up and you’ll need to follow the on-screen instructions to proceed with the upgrade process, which should take from a few minutes to even an hour or more, depending on your Internet bandwidth and the specs of your personal computer.
If, during the upgrade process, you are asked to replace any configuration files, do so. When the upgrade finishes, simply reboot your computer to enjoy Linux Mint 20.1 “Ulyssa” and its awesome new features.
After upgrading to Linux Mint 20.1, the Linux Mint devs recommend that you convert your system with the usrmerge utility by running the
apt install usrmerge command in the Terminal app. This is an optional step, and you can find more details here.
