Standard upgrade process

As a LTS user, I want to keep using these long term support version.

!cat /etc/issue
Ubuntu 18.04.5 LTS \n \l

A good way to do it is by using do-release-upgrade tool. Full explanation at: 18.04 to 20.04.

sudo do-release-upgrade
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release 
set Prompt=normal in /etc/update-manager/release-upgrades.

Waiting for blockers to be fixed

There is a last blocker before releasing Ubuntu 20.04.1 LTS.

{% include alert.html text=“Expected around 1st of October 2020.” %}

(2020-09-28) blockers are fixed, upgrade in progress

Unfortunately the upgrade process went uneventful. Nothing broke, nothing to learn ;)

It took minutes to do the upgrade.
