Use APT pinning in order to force package downgrade

Reinstall packages (testing → backports)

Temporarily force packages from stretch-backports to be installed even if same version is already installed from testing

cat <<EOF | sudo tee /etc/apt/preferences.d/pinning
Package: erlang*
Pin: release a=stretch-backports

Steps for migrating Prosody server to Ejabberd on Debian 9

First redacted on early March 2018.

After some time with Prosody 0.10 on Debian 9, I wanted to test Ejabberd. You'll find below steps for doing such migration.

Steps

Packages installation

The most recent version can be found in Stretch's backports repository:

cat <<EOF | sudo tee /etc/apt/sources.list.d/backports.list
deb http://ftp.debian.org/debian stretch-backports main
