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-upgradeon the 22.04 device. It does not increment it to22.04.4after reboot. - I don't want
sudo do-release-upgradeeither; this currently gives There is no development version of an LTS available, and would update to24.04.1if available, which I do not want. /etc/apt/sources.listseems to be identical between the22.04and22.04.4machines, with the exception that the comment at the top for the latter says it was installed via the22.4.04cdrom.uname -ron the22.04machine gives5.15.0-118-generic; The22.04.4machine is at6.5.0-44-generic, confirming that yes, the22.04machine 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-upgradeshould just work, but it doesn't seem to work for me?
