I am getting this error while automatically syncing with RTS (happens when I use FFS manually too).

I am using a usb as a bridge to sync some folders between a linux and a windows machine.
While syncing (two-way) on any of the two devices with the usb (called "sync") I get this error.

Could anybody provide me some information on this and how to fix it?
Thanks

Try deleting that file and running the sync again, which will create a new one

It seems you are running FFS on a Windows machine and on a Linux machine.
If I remember correctly, some FFS versions ago the sync.ffs_db file format was updated.
If your Windows FFS version uses the new sync.ffs_db file format and your Linux FFS version uses the old format (or vice-versa), the old FFS version can not read the new sync.ffs_db file format. This is the likely cause of your error.
Make sure to run compatible FFS versions on your two machines.
