In case you cancel the upgrade, remember that you have to manually enable the third part PPAs.
If you proceed with the upgrade, keep a watch on the screen for occasional
Y / N entry confirmation for overwriting packages.
Once the update is complete, do a reboot and enjoy the fresh Ubuntu 20.04 LTS Focal Fossa.
