    Try this command before you run do-release-upgrade -d

    sudo apt-get install --reinstall ubuntu-keyring

  2. I think you need to run do-release-upgrade -d with 'sudo'

  3. Same problem with 18.04.1 to 20.04. I have tried with and without sudo, but still getting error. I have also tried with update-manager -d, didn't work.

    Authenticating the upgrade failed. There may be a problem with the network or with the server.

  4. Try sudo apt install -f. This could fix some problems.
