This package from strongswan-epdg causes the SSH connection to QEMU to break when installed in debian 13. Don't install it. Use the wildcard, because there is also a debug symbols package that pulls in charon-systemd.
PyHSS listens on the same port as OsmoHLR, which causes the test to fail with debian 13 because OsmoHLR can't start up properly. PyHSS wasn't built for earlier debian versions in the Osmocom binary repositories.
