[Pkg-xmpp-devel] Bug#951154: prosody: ejabberd2prosody crashes

[Marvin Gülker]

Package: prosody
Version: 0.11.2-1
Severity: normal

Dear Maintainer,

the ejabberd2prosody script, which imports ejabberd data into prosody
with the goal of migrating from ejabberd to prosody, crashes. The
crash can be reproduced as followed:

0. Have ejabberd running with some users and their contacts.

1. Dump the existing ejabberd database:

  # ejabberdctl dump /tmp/dump.txt

2. Stop ejabberd and start prosody instead.

3. Try to import the dump.txt file with ejabberd2prosody:

  # ejabberd2prosody /tmp/dump.txt

The script then crashes with this error message:

    lua: /usr/lib/prosody/util/stanza.lua:27: module 'util.encodings' not found:
            no field package.preload['util.encodings']

    stack traceback:

            /usr/bin/ejabberd2prosody:28: in main chunk
            [C]: in ?

Expected result is that the script does not crash, but instead imports
the data into prosody successfully.

This was run on my Raspberry Pi 3B on an arm64 system.
