This has been tested and verified on an Ubuntu 18.04.1 LXC container on Proxmox. I was fed up from reinstalling it far too many times so I hope this is helpful @keycloak

Update to KC 9.0.2

Update to Keycloak 13. Boy it's been a while.

Major Update. Have not verified working and need to rework .service. May look at over forks for inspiration.
