Linux Mint new upgrade tool: LMDE 4 can be easily upgraded to LMDE 5
The Linux Mint team has announced a new upgrade tool that allows users of Linux Mint Debian Edition (LMDE) 4 to upgrade to LMDE 5 more easily. While the tool is currently only available for LMDE, the Linux Mint team is working hard to deploy it after the release of Linux Mint 20.3 to facilitate upgrades to 21.0.
While the graphical tool does simplify things, you still need to do a few things in the terminal when installing the upgrade tool. To install it, run the command below separately (sudo may be required, but the command below is provided directly by the Mint team):
apt install mintupgrade
You may be asked for a password to execute these commands, but once they are done, you will have the upgrade tool installed on your machine. Next, you want to start it from the command line, do it with the following command.
Now you can turn your attention to the graphical tool and follow the instructions to perform the upgrade. When it’s done, you need to uninstall the upgrade tool and restart your computer, which you can do with the following commands.
apt remove mintupgrade
During the upgrade process, you’ll be asked to make sure you’ve installed all available updates and backed up with a system snapshot in case something went wrong. Since this is a major upgrade, the Mint team emphasizes that you need to take your time and follow the rules.
