removed prosody repo, falling back to bionic package 0.10 / lua 5.1 works like a charm ;(

It's recommended to read the release notes before upgrading. Especially this part: https://prosody.im/doc/release/0.11.0#lua-5.2 The version of lua-cyrussasl in Debian (and Ubuntu) does not support Lua 5.2 so attempts to rebuild it have failed so far. Newer upstream version sounded promising, so I've filed this Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=916318
