Hi there, have a nuci7 on ubuntu 20.04 that I upgraded to 831 tonight, software update took but the db restore failed. Continues to fail to restore my DB after uninstalling and reinstalling roon. Tried different backups multiple times but end result is always “there was an issues loading your database”.
IMO, you’ve had what Roon calls ‘latent corruption’ for a while and the upgrade to a new Roon version uncovered that. Any Backup you have done while this corruption existed has, of course, been corrupted. You can’t find an un-corrupted Backup because the condition has existed long enough so that all the good Backups have been overlaid,
If that’s true in your case, it’s something that has always been a problem.
If your other Backups really are corrupted, then you should delete them and start fresh. Glad it worked out for you. I was not so lucky, once. I now Backup to many different places and on different schedules.
