The operating system Linux Mint has released a new version: Linux Mint 20.2 Uma. If you have release 20 or 20.1 installed, you can upgrade with the Update Manager. You can of course start a new installation directly with 20.2.
For all details about changes, release notes, detailed how to install and so on, please visit the Linux Mint website and their linked Linux Mint Blog. Troubles can be discussed in the Linux Mint Forum.
Before you update, do not forget to have fresh backup, license keys for software and so on that you do not want to loose, in case of trouble. Although computers are logical creatures, or because of that, upgrades can go wrong. Make sure also you are connected to power.
I started with my Lenovo ThinkPad T430s where I had Linux Mint 20.1 Cinnamon installed. When I started the upgrade, it worked extremely slow and I could find a message about the mirror was outdated. So I aborted the upgrade, changed to default sources for download and restarted. I installed all normal updates and then I went to the upgrade process again. This time the new release downloaded fast and installed fast as well, and the upgrade was completed in far less than ten minutes. Final step to restart, and no issue seen.
For my second laptop, Lenovo IdeaPad 100s where I had Linux Mint 20.1 Xfce installed, lesson learned and I started with changing to the default sources for download, I executed normal upgrades and then went on with the upgrade. For this very low spec laptop, the upgrade took just under ten minutes.
So, in short, a successful and smooth upgrade of Linux Mint,
Thanks Clem & Co!
