I upgraded my Linux server box to Ubuntu 8.10 tonight, and it went smoothly enough. Well, mostly… The big, complicated things like Apache, MySQL, and MythTV actually worked perfectly after the upgrade, and instead the glitches showed up in relatively small things, like the MP3 player. The files themselves were fine, but the collection database didn’t survive the change in version of Amarok, and I lost all of the non-ID3 metadata like ratings, play counts, etc.
I was able to recover some of it, from syncing back from the iPod and the playlist I still had loaded at the time, but it looks like I’ve lost about 2/3rds of the ratings. And I have backups of the MP3 files themselves, but not of the directory where it looks like Amarok stores the metadata, though it’s not clear if that would even help if it’s a version problem. Oh well, at least it’s easier to re-rate them on the fly through the iPod…
