I was trying to install xibo via snapd. first time I am actually utilizing linux but I had eventually wiggled through how to do It. My CMS is still 1.7 ( because I never used docker before) If you have a step by step tutorial on how to use docker can you please attach a link:
anyway: I got this message when I log on to virtualbox. I connected both player & CMS but nothing starts up ( default signage) & the player doesnt start up. just goes to this screen
