Its software has been updated and new improvements and features have been added focused on a much more enjoyable and functional user experience..

Through this tutorial TechnoWikis will explain how to upgrade from Linux Mint 19.3 to Mint 20.

 

 


1. Know Linux Mint architecture

 

This step is essential since if we are using 32-bit Linux Mint, the update process will simply generate errors, to verify that we use a 64-bit architecture, we will execute the following:

 dpkg --print-architecture 
image

 

 

As we can see, if it is 64 bits it will say "amd64"..

 

Note
In case of using a 32 bit version, it is recommended to install Linux Mint 20 from scratch, you can see it in the following tutorial:

 

 

 

 


2. Update Linux Mint 20 packages

 

Step 1

This process can be carried out through the console by executing the following:
 sudo apt update -y && sudo apt upgrade -y 
image

 

 

Step 2

Or failing that we can do it graphically using the Update Manager, for this we go to the start menu and in the "Administrator" section we go to the update manager:

Step 3

In the displayed window we will see the available updates:

Step 4

We click "Install updates" and we will see a warning about certain updates that require changes:

Step 5

We click OK and after this we must enter the administrator password:

Step 3

It is possible to simulate the upgrade to Linux Mint 20 Ulyana with the following command. We enter the letter “y” to continue. This simulation takes care of temporarily moving the current system to the Linux Mint 20 repositories and then restoring them to Linux Mint 19.3.

Note
This command, and the rest of mintupgrade, must be executed without sudo or without super user privileges.

5. Install and update Linux Mint 20 Ulyana repositories

 

 

Step 1

The first step to take will be to install the repository with the following command:
