"A" already mentioned that installing the ejabberd package from jessie
works. We also provide APT repositories for ejabberd, for wheezy we have
ejabberd 15.06, which requires erlang from backports. See


for more information. For the lazy:

Install Erlang from backports:

> apt-get -t jessie-backports install erlang

Install ejabberd:

This will of course also require upgrading your configuration as already
mentioned. Packages are also available for all other newer Debian/Ubuntu
