As mentioned in the README, Platypush requires a Redis server to dispatch messages across its components. If Redis is not running then Platypush can't work.

I installed redis as shown in the README, but failed to enable it. When running [sudo] systemctl enable redis terminal shows: Failed to enable unit: Refusing to operate on alias name or linked unit file: redis.service.

I also failed to find a solution in Redis' Issues, and the only close one I found was this issue at Icinga, which didn't work (changing icingadb-redis-server to redis-server and redis.service).

Found this issue also at Icinga, but it's still open.

Tried to run platypush again, apparently not running [sudo] systemctl enable redis nor
[sudo] systemctl start redis beforehand doesn't prevent Platypush from starting. Issue appears solved. I will close it now. Thank you @blacklight !
