怎样升级到Linux Mint 20.1

It is now possible to upgrade Linux Mint 20 to version 20.1.

If you’ve been waiting for this we’d like to thank you for your patience.

1. Create a system snapshot

You can use Timeshift to make a system snapshot before the upgrade.

If anything goes wrong, you can easily restore your operating system to its previous state.

Launch Timeshift from the application menu, follow the instructions on the screen to configure it and create a system snapshot.

2. Prepare for the upgrade

  • Disable your screensaver
  • If you installed Cinnamon spices (applets, desklets, extensions, themes), upgrade them from the System Settings

3. Upgrade the operating system

Upgrading to Linux Mint 20.1 is relatively easy.

In the Update Manager, click on the Refresh button to check for any new version of mintupdate or mint-upgrade-info. If there are updates for these packages, apply them.

Launch the System Upgrade by clicking on “Edit->Upgrade to Linux Mint 20.1 Ulyssa”.

Follow the instructions on the screen.

If asked whether to keep or replace configuration files, choose to replace them.

4. Convert the system with usrmerge (optional)

Although it is optional we recommend you convert your system with usrmerge. This is done already for all fresh installations of Linux Mint 20.1.

For information on usrmerge, read https://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge/.

To convert your system, open a terminal and type:

apt install usrmerge

5. Reboot the computer

Once the upgrade is finished, reboot your computer.

Commonly asked questions

  • If the upgrade is not available to you, check that you have the latest versions of mintupdate (5.7.3 or higher) and mint-upgrade-info (1.1.7 or higher) and restart the Update Manager by launching it again from the applications menu.
  • If the latest versions of mintupdate and mint-upgrade-info are not yet available in your mirrors, switch to the default repositories.
  • This happens rarely, but if you ever got locked and were unable to log back in, switch to console with CTRL+ALT+F1, log in, and type “killall cinnamon-screensaver” (or “killall mate-screensaver” in MATE). Use CTRL+ALT+F7 or CTRL+ALT+F8 to get back to your session.
