I'll suggest using apt full-upgrade
to ensure all upgrades are applied. There are cases where apt upgrade
can leave packages behind.
From man apt
you'll see the following
full-upgrade (apt-get(8))
full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole.
ie. if packages need to be removed from your system before later packages can be installed; upgrade
will leave them uninstalled... allowing you to install them when you decide using apt full-upgrade
.
Any 22.04 system with all upgrades applied reported itself as 22.04.1 during the weekend before actual 22.04.1 release; as the .1 upgraded packages had been rolling out for awhile, with the name change of 22.04 to 22.04.1 being the last change.
The release annoucments (I'll use a Ubuntu 22.04 here) say
As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation.
ie. the primary purpose is for new installs; so they don't need to install with older media (as you & most people had already done) then applied all upgrades to get there as you did. They could clean install & not have the huge upgrades of packages required with older media.
(FYI: the only reason I use that announcement is my browser knows of it without looking... I'm on the Ubuntu News team & actually posted it... why it's easy for me to grab/use as example)
re: Best Practice... If you apply all upgrades regularly; you were using it days before the release actually occurred !
