The same “exitcode 10” when trying to update happened in this thread and seemed to be a network issue. Your other issues (search lag, skipping tracks) also looks like a network issue. The “exitcode 10” was fixed by rebooting the router and then the ROCK, at least in this case:
Ben here with the support team, thanks so much for your patience! I was able to take a look into your account and see that your Nucleus is currently running build 1259, and was online recently.
How are things going? I’ll be on standby for a status update.
Hi Ben, the issues that I had seem to be straightened out with a static IP number change, ran test on my network and couldn’t find any issues that roon was saying about the network so I changed then IP number and things seem to be running Ok.
