In a hurry to upgrade from Ubuntu 18.04 to 20.04, because, you can?
Final question, and don’t phone a friend. Do you have a backup?
Ok then, here you go, 5 easy peasy steps:
sudo apt update && sudo apt upgrade sudo reboot command sudo apt install update-manager-core sudo do-release-upgrade
From here you’ll get lots of prompts but hopefully you know what you’re doing so all good.
sudo reboot
