Upgrade from 18.04 to 20.04

Asked by William Pabon

Hi!

A couple of years ago I tried to upgrade my system from 16.04 to 18.04 following the upgrade process, when I received the message that the upgrade was available. For reasons that today I don't remember, the upgrade went awry and it failed. I had to do a clean install, which had some challenges since my installation is in a Mac machine (dual boot with OSx). I am presently receiving messages from the S/W Center that the upgrade process to 20.04 is available, and I want to do it, but would like your advice to minimize the possibility of repeating my past experience. What preventive steps I should take before starting this project. Whatever wisdom you provide will be appreciated. Here is the info about my system.

Save all of your Documents, Pictures, Music, Videos, Etc. On a flash drive so you have them.

Skipping versions is not recommended.
Be sure you back all of your data that you intend to save.
   Download Ubuntu 20.04 LTS ISO to media, and install the new system. I’d use Manual Partitioning, selecting your existing partition(s), and ensure you don’t have format ticked.
This is FAR faster and will skip the missed releases. If you don’t format, it’ll note your added packages, wipe system directories, install, add back your additional packages (if available in your new 20.04 release) then ask to reboot. It won’t erase data unless you had ‘format’ checked, but as that’s easily missed, ensure you’ve backed up your data anyway.

Bernard010:

Thank you for the information. I am almost ready to do my upgrade using the process delineated on the link above. But first, as you advised, I'm going to back up my /home directory for safety. Hopefully, it should be smooth sailing this time and I won't need to use my backup data. As soon as this upgrade is completed, I will close the issue. Thanks again for the help.

If you have been prompted to Upgrade through your updates it works. It is a timely process more than 3 hours.
