Upgrade from Ubuntu 18.04 to 20.04

Hello penguins, I hope this short post helps someone.

As you know, I have been using Ubuntu since 2004, and I must confess that I like it more every day.

I have already some years (5 years at this time) that I left the country where I was born (Venezuela). Now, I live in the United States of America. Place where I have been able to lay roots and start a new life.

In my professional world, I had the opportunity to start and advance many new projects. But always have something is common, it is that in many project, some partners who always look at me strangely, when they see my computer desktop and that does not use Windows.

So they usually ask me, “And what is that?” Obviously, I answer “LINUX, Ubuntu”.

Today, I would like to leave here, the procedure of how I updated my Ubuntu 18.04 to the new version 20.04.

First of all, what I did was make sure that my ubuntu was completely updated, for this I updated my repositories, opening a Terminal and then I ran:

sudo apt update

Once the repositories were updated, then proceeded to upgrade the complete system with the command:

sudo apt upgrade 

Because I had packages pending upgrade, they were downloaded and updated.

When this was ready, then take advantage of uninstalling everything that was not needed by the system, executing the command:

sudo apt autoremove

I really prefer having the most amount of space on my hard drives before upgrading, so clear the APT system cache by running:

sudo apt clean

At the end of the uninstallation an cleaning process, then restart my computer, I logged in again and reopened my terminal (I use “Deepin Terminal” with FISH). Then I had everything ready to start the installation (Upgrade) to Ubuntu 20.04. So I ran:

sudo do-release-upgrade -f

This procedure asked me several confirmation questions as well as made it clear that it would take some time to complete.

Please wait patiently (it took about an hour) and when finished my computer rebooted. So when I returned, everything was ready. Everything worked perfectly.

My only recommendation is for those who do not have a fast internet, in which case I would recommend doing such an update from an external medium or a clean installation (If you are going to do a clean installation, remember to back up your data and then be able to restore them)
