The percona-release package appears to be missing from the prel repository on Debian Trixie. This means the package won’t be updated automatically, and also gets picked up as a package that’s not in a repository, eg with apt list ?obsolete.
Eg testing with:
# curl -s -O https://repo.percona.com/apt/percona-release_latest.generic_all.deb
# apt install ./percona-release_latest.generic_all.deb
On Debian Bookworm, percona-release is in the prel repo:
# apt policy percona-release
percona-release:
Installed: 1.0-32.generic
Candidate: 1.0-32.generic
Version table:
*** 1.0-32.generic 500
500 http://repo.percona.com/prel/apt bookworm/main amd64 Packages
100 /var/lib/dpkg/status
...
But on Debian Trixie, it’s missing:
# apt policy percona-release
percona-release:
Installed: 1.0-32.generic
Candidate: 1.0-32.generic
Version table:
*** 1.0-32.generic 100
100 /var/lib/dpkg/status
Despite the prel repository being enabled:
# percona-release show
The following repositories are enabled on your system:
prel - release
telemetry - release
<*> All done!
This can also be seen from browsing the repository web view - eg the Packages file at https://repo.percona.com/prel/apt/dists/trixie/main/binary-amd64/ has a size of 0, while at https://repo.percona.com/prel/apt/dists/bookworm/main/binary-amd64/ it’s non-zero - so Trixie’s prel repository is entirely empty.
