How To Upgrade Raspberry Pi Ubuntu Mate

Before doing anything, create a backup. You can restore your server in case anything goes wrong. Go to the shell and start by running this command with no options:


  • sudo do-release-upgrade


If the new Ubuntu has not been released yet, you should see the following:
Sample Output
Checking for a new Ubuntu release
No new release found
In order to upgrade to  the last version  before its official release, specify the -d option in order to use the development release:

  • sudo do-release-upgrade -d


If you’re connected to your system over SSH, you’ll be asked whether you wish to continue.
Follow the on-screen instructions.

You will now see the packages that are going to be upgraded and the changes that are going to be made. Note that the upgrading process can take several hours, and you can’t cancel the process once Ubuntu is upgrading.

After the upgrade has finished, you can confirm your server is running on the new version by executing the command

lsb_release -r
