A huge amount of work has gone into it, and now Sympl is ready for beta testing.
As before, you shouldn’t run this in production (yet) but it should operate mostly the same as Symbiosis did.
With a fresh Debian 9 server, run these commands and you should end up with machine running Sympl:
wget -qO- http://firstname.lastname@example.org | apt-key add -
echo deb http://packages.mythic-beasts.com/mythic/ stretch-testing main > /etc/apt/sources.list.d/sympl_mythic-beasts.list
apt-get install --install-recommends sympl-core
If you run into any issues, please log them here or find me in #Sympl on freenode.
