Upgrading the ubuntu version has many challenges. I want to know whether kernel and grub versions are autonomously upgraded when upgrading the ubuntu version, ignoring those upgrade difficulties.

ubuntu uprade Examples :

16.04 -> 18.04

18.04 -> 20.04

16.04 -> 18.04 -> 20.04

Why not look; eg. https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=grub2 will show the grub version for many releases and show what will upgrade (*terminal enquiries will show more releases than the link I provided too*)

@ guiverc I looked this site, too. But, I wander the case that after installing the ubuntu, the version is directly upgraded, no any installation. I think that it is not explicit. Besides, there is no 16 version on this site. On the old page, the grub part doesn't seem to be specified.

Ubuntu 16.04 LTS has ended it's *standard* (public/free) supported life (https://fridge.ubuntu.com/2021/03/13/extended-security-maintenance-for-ubuntu-16-04-xenial-xerus-begins-april-30-2021/) which is why it doesn't show, a CLI enquiry however will show it. Those packages show what is installed on a new install, what you get when upgrading (the -updates link) for each release; which includes of course *release-upgrades*, ie. moving from 18.04 (*bionic*) to 20.04 (*focal*) will cause your packages to upgrade to the *focal-updates* version as per that page.

Online you can find versions using https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=grub2 for grub2 which show the versions for each release.

Using a command line enquiry I get even more results

Ubuntu 16.04 LTS has ended it's standard (public/free) supported life (https://fridge.ubuntu.com/2021/03/13/extended-security-maintenance-for-ubuntu-16-04-xenial-xerus-begins-april-30-2021/) which is why it doesn't show on the online enquiry (it does from terminal as it's still got ESM or extended support if you have ESM enabled).

Those packages show what is installed on a new install, what you get when upgrading (the -updates link) for each release; which includes of course release-upgrades, ie. moving from 18.04 (bionic) to 20.04 (focal) will cause your packages to upgrade to the focal-updates version as per that page.

If you install Ubuntu 18.04 LTS using initial media, the version I'd expect is

grub2 | 2.02-2ubuntu8 | bionic | source

but if you applied upgrades to the system, I'd expect the following version

grub2 | 2.02-2ubuntu8.25 | bionic-security | source

If you release-upgraded to Ubuntu 20.04, I'd expect the following version to exist on the system

grub2 | 2.04-1ubuntu26.15 | focal-updates | source

The URL I provided contains all the detail you wanted; I just opted to use the same input provided from a terminal command as I find it easier to copy/paste from. Note: I've assumed amd64 architecture; though in this case it doesn't matter (but i386 for example isn't supported in focal (20.04) thus has no listing there).

Also maybe of note.... I used the term "*initial media* meaning Ubuntu 18.04 LTS media; if you used Ubuntu 18.04.1 LTS media, through to Ubuntu 18.04.5 LTS media the installed version can vary as it'll be whatever was in -updates at the time. My use of "*initial media*" was to refer to the initial media on actual release; not the re-spins. If I wanted to know what version was on a later ISO (eg. 18.04.3 for example which is an older ISO) that wasn't updated, I'd look at the *manifest* for that version ISO.

If of interest; the command I use is `rmadison grub2` to get the results I posted... I find it very handy given I'm usually running the *development* release which isn't included on the URL I usually post here. By default that script isn't installed (*devscripts*) but is easily installed.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
