Linux Mint 21 is out
I installed Linux Mint Cinnamon 21 on August 2nd. Install went smoothly and so far no problems to report.
I just upgraded my Mint distros from 20.3 to 21 …all went well so far.
I tried he Mate update to 21. It took a long time and eventually hung/froze. I chose to install fresh. With having a home partition it took less time than the upgrade was taking. After upping; a few installs and Bob’s your uncle; running Mate Venessa.
Yesterday, I run the upgrade option for my desktop for Linux Mint from 20.3 to 21.
The process took less then an hour to complete and went very smoothly. The upgrade identified 3 programs that I would need to re-install after the upgrade. I run a very “vanilla” install of Linux.
The commands I used to upgrade.
sudo apt update
sudo install mintupgrade
sudo apt remove mintupgrade
Then just re-boot the system.
It is ALWAYS a good practice to make a backup of your system before making any changes.
I used the upgrade option for Debian 10 to 11, and for Devuan 3 to 4.
They both went smoothly
In Debian I lost some scanner drivers that were installed outside the package system. That is understandable. They were easily put back.
In Devuan nothing u toward happened.
I agree with @easyt50 . Use upgrade, but do a backup first.
