That title is an error message from Emby, the music, movies, and more, server that I use on my systems, so all our music is available. It’s really very, very good. But sometimes it stops working. And you get that error message.
All over the internet, you can find people searching for that message, asking what it means, and how to fix it. What you won’t find is anyone giving a simple, direct answer, not even the people who wrote it.
I don’t claim to know the answer in every case. But I can tell you what caused it on my system, and how I fixed it. It is worth seeing if you have the same problem…
When I set up Linux Mint on my big PC, the hard disc the music is on appeared to be in the /mnt directory. I didn’t decide that, it’s just how it set itself up.
I had a look at the directory structure, and found that the hard disc now appeared in the /media directory. I hadn’t moved it.
So, I told Emby to forget its libraries, and then added them in again with the right path.
It worked.
