Let's test fedora-42

It's actually all the same issue: we expect to see a hostkey prompt when connecting to a secondary host and we don't see it. The obvious thing that would be wrong here is that we're not checking keys properly, but we're also failing in one of the tests to login with the expected credentials, which suggests to me that we're somehow not ending up on the expected host...

[allisonkarlitskaya]

Nope. It's not actually because of a bad username or password. That's just the generic error that's printed when cockpit-ws doesn't know why auth failed. The real reason is this:

FileNotFoundError: [Errno 2] No usable temporary directory found in ['/tmp', '/var/tmp', '/usr/tmp', '/']

from cockpit.beiboot.

The actual failing syscalls:

openat(AT_FDCWD, "/tmp/dgud7zua", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW|O_CLOEXEC, 0600) = -1 EACCES (Permission denied)
openat(AT_FDCWD, "/var/tmp/ztwihmrr", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW|O_CLOEXEC, 0600) = -1 EACCES (Permission denied)
openat(AT_FDCWD, "/usr/tmp/pwmh9eez", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW|O_CLOEXEC, 0600) = -1 EACCES (Permission denied)
openat(AT_FDCWD, "/16agvjoh", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW|O_CLOEXEC, 0600) = -1 EROFS (Read-only file system)

turning selinux enforcing off fixes it, predictably.

@allisonkarlitskaya This is https://issues.redhat.com/browse/RHEL-72967 which apparently affects Fedora 42 as well. We need a hack similar to cockpit-project/bots@eb3cedd2d on the f-42 image.

@martinpitt the issue should be fixed with latest systemd main as PR for this was merged couple days ago.

systemd/systemd#36100

Also this has been backported to systemd-v257-stable branch and it should appear in Fedora once @keszybz does the rebase.

systemd/systemd@47792af

We added the workaround via bots (and it just went green), so let's close this one.
