This package failed build from source when test-built against a version of
python3-defaults that incudes 3.13 as a supported version.

To reproduce this issue, build against python3-defaults (python3-all-dev etc.)
from Debian experimental.

This bug has been filed at "normal" severity, as we haven't started the
transition to add 3.13 as a supported version, yet. This will be raised to RC
as soon as that happens, hopefully well before trixie.

Thanks,

Stefano

Dead upstream, NMU-maintained after 2021, low popcon.
Same for its revdeps some of which aren't even in testing.

dak rm -Rn libprelude libpreludedb prelude-correlator prelude-lml prelude-manager prewikka sagan samhain

(unless fixed before this bug becomes RC)

Hi,

I think I might remember that another RM bug
involving samhain/sagan was dismissed because DSA
uses it on Debian infrastructure itself...

https://dsa.debian.org/ports/hardware-requirements/

Yes. That was #1082808 and as a result samhain no longer depends on
libprelude. So it's now just

dak rm -Rn libprelude libpreludedb prelude-correlator prelude-lml prelude-manager prewikka

It would be, if the newer samhain would migrate to testing, but
right now it ftbfs on s390x.

I am including a patch for this.
