Ubuntu 20.04.01 and Ubuntu 20.04.02 on my desktop?

It seems to me I miss something.

lsb_release, /etc/issue File, /etc/os-release, hostnamectl and in the Ubuntu interface Settings > About, I return - Ubuntu 20.04.02 LTS - as Ubuntu long version

But, the last Ubuntu release is 20.04.1 LTS (https://wiki.ubuntu.com/FocalFossa/ReleaseNotes)

and, with

jre@jre:~$ apt show firefox
Package: firefox
Version: 84.0.2+build1-0ubuntu0.20.04.1
...

This command references 20.04.1 ?!

Thank you for your feedback

--- Oups! Edited ---

uname -a return 20.04.1

jre@jre:~$ uname -a `20.04.1`
Linux jre 5.8.0-41-generic #46~20.04.1-Ubuntu SMP Mon Jan 18 17:52:23 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Not as mentioned in my initial message.

Solution 1:

Ubuntu release dates (for point releases) refer to the ISO release date. The Ubuntu 20.04.2 LTS ISO hasn't been released (it's scheduled for this thursday), but installed systems will already have upgraded to be using it, as is normal.

Package names however are not the same thing, ie. you're comparing a firefox package name, to the release version.

Your apt command is showing the package version which will be according to a standard, but different teams/packagers can use different standards, so unless you're familiar with the team that created the package, don't get fixated on package names. All parts of the "84.0.2+build1-0ubuntu0.20.04.1" will have meaning if you break it down, but few of us thankfully have to :)
