Ubuntu

[Micha Bailey]

Regarding the upgrade to Focal (20.04): There’s no reason to rush. Bionic
(18.04) is supported, if I’m not mistaken, until 2023. In fact, Bionic
(LTS) users aren’t even offered the upgrade (i.e. you need to go out of
your way to get it) until 20.04.1 is out in a few months.

Regarding the upgrade to 18.04.4, I could be mistaken, but my understanding
is that point releases aren’t new versions of Ubuntu per se. At point
releases, new isos are spun with up-to-date packages, but it’s still the
same version. Assuming you make a habit of installing updates regularly
(which you obviously should be), you will effectively automatically be on
18.04.4.
