How can I update to the latest point release, keeping my Ubuntu version the same?

Context: I'm trying to track down a bug that only appears on one of two seemingly identical Ubuntu installations on thinkpads. The first difference I see between the systems is that the bug appears on the device running Ubuntu 22.04 LTS and not on the device running Ubuntu 22.04.4 LTS as reported by cat /etc/lsb-release.

What I've tried

  • I've run apt update, apt upgrade, apt dist-upgrade on the 22.04 device. It does not increment it to 22.04.4 after reboot.
  • I don't want sudo do-release-upgrade either; this currently gives There is no development version of an LTS available, and would update to 24.04.1 if available, which I do not want.
  • /etc/apt/sources.list seems to be identical between the 22.04 and 22.04.4 machines, with the exception that the comment at the top for the latter says it was installed via the 22.4.04 cdrom.
  • uname -r on the 22.04 machine gives 5.15.0-118-generic; The 22.04.4 machine is at 6.5.0-44-generic, confirming that yes, the 22.04 machine is not fully upgrading.

Question summary

Is there an update path to turn, for example, a 22.04 system into a 22.04.4 system? Or does the third point release number not mean much here, or is it simply that the update process forgets to change it?

Prior research

  • Note that this question isn't about LTS or stable releases per se, but rather whether it is possible to increment the point release of a specific Ubuntu version currently installed, ensuring that the machine does not increment to the next major LTS version.
  • This question mentions point releases but I don't quite understand it.
  • I did not understand this question about updating point releases and as far as I can tell a method to increment to the latest LTS point release wasn't clearly given.
  • This question seems relevant at first, but it looks like the solution there would either update to 24.04.1 (which I do not want)`, or do nothing (the behavior I get now). This related thread also did not resolve my question.
  • This thread for Ubuntu Mate seems to imply that apt full-upgrade should just work, but it doesn't seem to work for me?

You can not be accidentally upgraded to a new release.

There is no actual method to go to the next point release.

If all the apps are updated then it is the next point release. Simply doing a sudo apt get update and a sudo apt get upgrade should be all you need to do.

Assuming no errors and no updates being held back you will have Ubuntu 22.04.4

As of today there is no supported upgrade from 22.04 to 24.04 unless you force it. That feature is scheduled to be released on August 15, 2024.
