My Roon Core is installed in Qnap 262C with 8G RAM. Everything was fine until the update of Roon 2.0 was launched. The original version of 1.8 cannot be used any more, but the core can’t update to 2.0. I have been updating it for days, but nothing worked out.
Downgrade your mobile to 1.8, then upgrade your core, before updating other devices.
