chore: remove Fedora 38 & kmods images

[p5]

Remove kmods builds
Remove Fedora 38

Do not merge until a few weeks after Fedora 40 dropped

Relates: #527

[p5]

I know we don't really need this, but no point ripping this out when it'll be added in 4 months again.

Is this for the Fedora 40 release?
Then latest will de F40 and gts F39?

[bsherman]

@p5 I don't think we should tie the release/promotion of F40 to stable/latest to removing F38 builds. Shouldn't removing F38 be a distinct act?

As much as I want to stop maintaining 38, I really am hesitant to drop those builds this week... feels like we should get a bit closer to upstream's EOL first.

latest will be F40 and gts F39?

yes

Understood. I thought Fedora maintained two releases at once, therefore F38 will be EOL'd tomorrow, but it must be three versions at once.

So including only the Containerfile ARG defaults

ARG FEDORA_MAJOR_VERSION="${FEDORA_MAJOR_VERSION:-40}"

FROM ${BASE_IMAGE}:${FEDORA_MAJOR_VERSION}

ARG IMAGE_NAME="${IMAGE_NAME:-silverblue}"
ARG FEDORA_MAJOR_VERSION="${FEDORA_MAJOR_VERSION:-40}"

and

          if [[ "${{ matrix.fedora_version }}" -eq "39" ]]; then
            IS_LATEST_VERSION=false
            IS_STABLE_VERSION=true
            IS_GTS_VERSION=true
          elif [[ "${{ matrix.fedora_version }}" -eq "40" ]]; then
            IS_LATEST_VERSION=true
            IS_STABLE_VERSION=true
            IS_GTS_VERSION=false
          elif [[ "${{ matrix.fedora_version }}" -eq "41" ]]; then

is enough for tomorrow?

Yeah, there's usually around a month of overlap.

Yes, but I want to review the final PR again, i think maybe some copy paste issues in the comment above.

Have repurposed this PR to only deprecate Fedora 38 and kmod builds. Will bump Fedora 39 and 40 in this PR

[bsherman]

@p5 I would suggest that "deprecate" means "not recommended for use" but this PR will remove 38 so it cannot be used.

[dylanmtaylor]

You should delete lxqt from the image_name list.

You should delete lxqt from the image_name list.

Good catch

Regarding the "when" of removing Fedora 38... we recently updated our governance document to make this more clear:

Our goal is to build two currently supported versions of Fedora, the most recent and one previous version.

https://universal-blue.discourse.group/docs?topic=51

Given this update, we should be good to remove immediately.
