Bug#1118567: udd: archive-ubuntu importer isn't working

Package: qa.debian.org
Severity: important

https://udd.debian.org/udd-status.cgi is reporting that the
archive-ubuntu importer isn't working. It provides this log excerpt:

/srv/udd.debian.org/udd/udd/archive_gatherer.rb:290:in
`exec_prepared': ERROR:  duplicate key value violates unique
constraint "ubuntu_packages_pkey" (PG::UniqueViolation)
DETAIL:  Key (package, version, architecture, distribution, release,
component)=(3cpio, 0.10.2-0ubuntu1, amd64, ubuntu, questing, main)
already exists.

from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:290:in `block in
process_packages'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:240:in `each'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:240:in `process_packages'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:402:in `block in run_path'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:400:in `each'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:400:in `run_path'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:299:in `run'
from /srv/udd.debian.org/udd/udd/archive_gatherer.rb:412:in `<main>'

That source package (rust-threecpio) version is present in both
questing and resolute.

I assume this began failing after
https://salsa.debian.org/qa/udd/-/merge_requests/64 was merged.

https://udd.debian.org/dmd/?gstreamer1.0%40packages.debian.org shows
that there is content for questing but not for resolute yet.

Thank you,
