Package: puppet-master-passenger
Version: 5.5.22-1
Severity: normal

Dear Maintainer,

I upgraded my system running puppet-master-passenger from Buster to
bullseye. From that moment on, puppet-master-passenger crashed when a
client tries to retriveve its configuration. The follow stacktrace could
be found in the Apache error.log:
