Currently, the installation via WebUI is mostly pushing the Next button
which seems to be ok for the production which is based in the US.
This PR makes openQA to select languages when the G-I-S runs
before Anaconda. The particular language is selected based on
the LANGUAGE variable.
The latest version of g-i-s grew a "Previous" button on the
final page, and hitting tab once now activates that, not the
Try button. shift-tab *should* get us to Try on both old and
new versions.

We're reverting webUI for Fedora 39.

We now have a fix for the bug on the new webUI flow where the
language and keyboard screens weren't skipped on the first boot
after install, as intended. language is never *really* skipped -
it just turns into welcome - but keyboard is now being skipped,
which messes up the logic here.
For a short time we need to handle both paths, to get the new
anaconda builds through and new composes built. In a couple of
days we can simplify this to just always assume keyboard will
be skipped on the first boot on Workstation live installs on
F39+.
Also drop handling of auth_required in g-i-s - I'm pretty sure
that bug got fixed years ago - and wait_still_screen for three
seconds on each page, to let animated transitions settle.

We're seeing a lot of tests fail on 404s when trying to access
the koji-rawhide repo (the repo for the Rawhide build tag, which
we use to get packages tagged since the last compose. nirik is
trying to figure this out from the server end, but for now at
least, let's mark the repo as skip_if_unavailable. This should
mean that if we hit a 404, the test will continue, it just won't
have access to the packages from that repo. Occasionally this
will cause a problem - a false failure or false pass - but this
still seems better than every test that hits it failing. The
false pass case is the most concerning, but I would hope in that
case some other tests from the same update would fail, making it
not an issue.

Instead of having each update test recreate them for itself -

So...there's an ffmpeg update:
https://bodhi.fedoraproject.org/updates/FEDORA-2023-a5e10b188a
which went stable. It includes new sonames of all the ffmpeg
libs. It also pulls in a thing called oneVPL, which has a bug
that breaks ostree composes.
There's a big kf5 update:
https://bodhi.fedoraproject.org/updates/FEDORA-2023-b086a98f78
which contains kf5-kfilemetadata, which is built against ffmpeg.
Neal made sure that update's build of it was built against the
new ffmpeg and submitted both for stable at once - but the tests
on the kf5 update failed because they weren't run against the
new ffmpeg as it wasn't yet stable, and the kf5 update was
ejected from the push because of the failed tests.
So now we have the ffmpeg update stable but not the
kf5-kfilemetadata rebuild for it, which will break KDE stuff,
and the oneVPL issue means ostree composes will all fail.
This adds the ffmpeg update as a workaround so we can re-run the
tests for the kf5 update and get them to pass so we can push it
stable. It also adds the oneVPL update as a workaround so ostree
compose tests don't start failing.

A different way to address the same problem as 56936df7 . Let's
just *remove* the repo management packages after we're done
creating the repos. dnf will automatically remove the unused
dependencies too. This fixes the python-cryptography case at
least - I tested.
Signed-off-by: Adam Williamson <awilliam@redhat.com>
There's this awkward path for the live image install tests on
updates. We run the 'are the correct versions of all the packages
installed' check on these tests to ensure the right versions
actually made it onto the live image. So we don't run
`dnf -y update` at the end of repo_setup_updates on that path,
because if we did that, even if the packages on the live image
were old, we'd update them there and hide the problem.
However, this causes a bit of an ordering issue, because in
order to set up the advisory repo, we need to install a few
packages. What if the update under test includes one of those
packages, or a dependency that wasn't already installed? In
that case, we wind up with the older stable version of the
package (because obviously we can't install the newer version
from the advisory repo *before we've set up the advisory repo*),
don't update it later, and so the 'correct version' check at
the end of the test fails. See:
https://openqa.fedoraproject.org/tests/1778707 for a case of
this happening with a python-cryptography update.
Up till now I was trying to handle this by just updating the
specific packages we install, but that doesn't account for
*dependencies* of them. I looked down the path of trying to
generate a list of all those dependencies and update all of
them but it looks a bit mad. So instead let's try this. On that
specific path, we'll generate the "all installed packages" list
*before* we run repo_setup, so it just doesn't include anything
that gets installed during repo_setup. The implementation is a
bit icky but not too horrible.
We *could* just *always* generate the all installed packages
list earlier, but then that would mean we *wouldn't* catch dep
issues in this kind of package on the other test paths, whereas
currently we do. I don't want to lose that.

Signed-off-by: Adam Williamson <awilliam@redhat.com>
With Rawhide updates, we quite often run into a situation where
a test runs after a *later* version of the package has already
gone stable. This even happens for stable releases too, though
less often. The current shell-based check just always fails on
this case, but it's usually OK, and manually marking every case
like this with an "it's OK!" comment gets tiring. Instead, let's
use a smarter Python script to do the check. We compare the EVR
of all installed update packages with the EVR of the package
from the update. If it's the same, fine. If the installed package
is lower-versioned, that's always an error, and we fail. If the
installed package is higher-versioned, we check whether the
update already went stable. If it did, then we soft fail, because
probably nothing can go wrong at this point (this is the usual
Rawhide case). If the update did not yet go stable, we still
hard fail, because something can go wrong in this case: if the
update *now* goes stable, the older version from the update may
be tagged over the newer version the test got (presumably from
current stable).
If anything goes wrong with the Bodhi check, or the test is
running on a task not an advisory, we treat both cases as fatal.
The script also gives easier-to-understand output than the old
approach, which should be a bonus.

This is safer if the advisory stuff was done on a previous test
run. Hilariously, this exposed a dumb mistake I made years ago
in installedtest.pm and never noticed before: the calls to
advisory_* at the bottom of that file are meant to be in the
post_fail_hook, but they weren't, which meant they got called
by the scheduler. This didn't cause any failures because the
first line caused them to return immediately based on a get_var
call (which it's OK to do in the scheduler), but changing it
to a script_run call (which it's *not* OK to do in scheduling)
caused all the tests to blow up immediately and confused me
*a lot* until I spotted this!

When I enabled _advisory_post for live and ostree install tests,
the point was to check that updated packages were included in
the install media and used during installation. We shouldn't run
a system update in _repo_setup_updates on this path because it
will hide the problem if the updated packages weren't included.
The INSTALL variable is for this purpose - it was previously

Per discussion at https://pagure.io/fedora-ci/general/issue/376
it really feels like this is the right thing to do. There are no
buildroot overrides for Rawhide, so we don't have to worry about
cross-pollution. The buildroot repo only contains builds that
have been tagged stable since the most recent Rawhide compose,
and thus will go into the next one. It makes sense to test later
updates against these. This avoids issues like:
https://openqa.fedoraproject.org/tests/overview?distri=fedora&version=38&build=Update-FEDORA-2022-30a952e331&groupid=2
where the tests of an update failed because it requires another
update which had been submitted and tagged stable previously, but
after the last compose.

This is like the existing tests that build network install and
live images then install them, only for Silverblue. First we
build an ostree, using the standard configuration for the release
and subvariant but with the 'advisory' and 'workarounds' repos
included, so it will contain current stable packages plus the
packages from the update and any workarounds. Then we build an
ostree installer image with the ostree embedded, again including
advisory and workarounds repos in the installer build config so
packages from them will be included in the installer environment.
The image is uploaded, which completes the _ostree_build test.
Then an install_default_update_ostree test runs, which does a
standard install and boot from the installer image.
We do make a change that affects other tests, too. We now run
_advisory_post on live image install tests, as well as this new
ostree install image install test. It was skipped before because
of an exception that's really only needed for the netinst image
install test. In that test, packages from the update won't be
included in the installed system, so we can't run _advisory_post
on it. But for ostree and live image build/install tests, the
installed system *should* include packages from the update, so
we should check and make sure that it does.

This issue appeared when we started testing Rawhide updates, but
I only noticed it today. When testing Rawhide updates after
Branch point, the upgrade tests upgrade from Branched to Rawhide.
On Branched, updates-testing is enabled by default. We only
disable it when we reach `upgrade_run`, but by that point we've
already done a `dnf -y update` in `upgrade_preinstall` and
potentially installed other packages in steps between
`upgrade_preinstall` and `upgrade_run`. That can cause problems,
like today all FreeIPA upgrade tests on Rawhide are failing
because there's a newer freeipa in updates-testing for F37 than
is in the current Rawhide compose.
Solve this by disabling updates-testing before we do the update
in `upgrade_preinstall`. To avoid excessive code duplication,
factor out the repo disabling code.
We'll do this twice on upgrade tests now, but it shouldn't be a
problem.

It also adds a helper script to the utils.pm
* make_serial_writable
that makes the serial console writable for normal users
and so enables to run commands that check their progress
by sending messages to the serial console. Normally, they
fail, because the messages will not be written their, so
the checking mechanism will never see them.
