I'm also very interested in solving this, because it's blocking net-snmp and a bunch of other packages from migrating. Last week I did some investigation and pretty much stopped at the same point as Lukas did. I wasn't able to pinpoint exactly what the root cause is, but Timo's guess is a good starting point. I fiddled a bit with autopkgtest.db and confirmed that the failures started with 389-ds-base/1.4.4.4-1: sqlite> SELECT test.package, result.version, result.triggers, result.exitcode FROM result INNER JOIN test ON test.id = result.test_id where test.package = 'dogtag-pki' and result.triggers LIKE '%389-ds-base%'; I'll see if I have the time to investigate a bit more.
