It has been a long time since its release Linux Mint 20. Finally, the team distribution development published instructions for the update. Notably, this time you can only upgrade Mint 19,3 64-bit.
Users running the 32-bit distribution are not so lucky.
Η αιτία αυτής της αλλαγής είναι προφανής, αφού το Linux Mint 20 βασίζεται στο Ubuntu 20.04 LTS, και τα δύο λειτουργικά συστήματα υπάρχουν μόνο σε εκδόσεις 64-bit. Το Linux Mint 19.3 is the last version that supports the 32-bit architecture and will be available until April 2023.
If you are satisfied with the current installation of Linux Mint 19.3 and you don't need to upgrade to version 20 since you can safely use your current OS for a year or two.
Otherwise, you should take a look at the detailed guide below
