## Expected Behavior I tried installing a test version of Gluu using Ubuntu 20.04 (Windows Linux Sub system), using the guide video here: https://www.youtube.com/watch?v=auJ5bl41lK8 curl https://repo.gluu.org/ubuntu/gluu-apt.key | sudo apt-key add - sudo apt-get update sudo apt-get install gluu-server Expect: the installation completes successfully ## Actual behavior The installation failed with below error (see full log below) ``` System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down dpkg: error processing package gluu-server (--configure): installed gluu-server package post-installation script subprocess returned error exit status 1 ``` Could you please check?
