Linux Mint team announces new upgrade tool , allows users of Linux Mint Debian Edition (lmde) 4 to upgrade to lmde 5 more easily Although the tool is only applicable to lmde at this stage, the Linux Mint team is trying to deploy it after the release of Linux Mint 20.3 to facilitate the upgrade to 21.0.
Although graphical tools do simplify things, you still need to perform some operations in the terminal when installing the upgrade tool. To install it, run the following command separately (sudo may be required, but the following command is provided directly by the mint team):
apt update
apt install mintupgrade
You may be asked to enter a password to execute these commands, but once they are complete, you will install the upgrade tool on your machine. Next, you start it from the command line and do it with the following command.
sudo mintupgrade
Now you can turn your attention to the graphical tool and follow the instructions to perform the upgrade. When it is finished, you need to uninstall the upgrade tool and restart your computer. You can do it with the following command.
apt remove mintupgrade
sudo reboot
During the upgrade process, you will be asked to ensure that you have installed all available updates and backed up with a system snapshot in case of problems. As this is a major upgrade, the mint team stressed that you should take your time and strictly follow the regulations.
