Trying to get some clarity on the meaning of LTS and the point release of 18.04. Looking on Canonical site they state 5 years support for 18.04, 18.04.1 and 18.04.5 but only six months for 18.04.2/3/4. See:
https://wiki.ubuntu.com/Kernel/Support#A18.04.x_Ubuntu_Kernel_Support
I'm trying to understand a couple of things:
- Does the Ubuntu bionic version migrate through point release numbers based on "apt upgrade" and thus a normal user with unattended-upgrades set would just migrate through these bionic releases? It does not appear that you need to use dist-upgrade to get to next bionic point release.
- Based on answer to above, how would a user stay on 18.04.1 and get security patches without migrating to next bionic point release and latest kernel?
- When would a 18.04.1 device be expected to get the v5 kernel (seems this came with 18.04.3) and what if anything, would stop this kernel upgrade via apt?
My assumption has always been:
- that bionic releases upgrade automatically through apt and ppa definitions
- all 18.04 releases are considered LTS (not clear what the 6 month kernel timeline means from a support perspective as devices would get to .5 and be supported going forward)
I am asking as there is a vendor who is refusing to support v5 kernel based on the above chart and yet claims support for "18.04 LTS". Can't find a good answer on whether 18.04.3 is or is not considered an LTS release.
Thoughts?
