"syncing: no connected device has the required version of this file"

I deleted 2 files from a PC running Syncthing v2 RC22. Soon after, the folder is marked “out of sync” with 2 failed items. Both items have the message “syncing: no connected device has the required version of this file”. If I created 2 dummy files with the same names as the deleted ones, the folder is in sync again.

And if you delete them again?

Output from syncthing cli debug $folderID $pathToFile (the path being that inide the folder)?

If I delete the dummy files, the folder will be out of sync.

How do I use the syncthing cli debug command? I tried D:>c:\PortableApp\SyncTrayzorPortable-x64\data\syncthing cli debug $tnhbr-gxtuf d:\win_apps\XnViewMP-win-x64.exe

and got

syncthing: error: unexpected argument $tnhbr-gxtuf

D:>c:\PortableApp\SyncTrayzorPortable-x64\data\syncthing.exe cli debug tnhbr-gxtuf XnViewMP-win-x64.exe

That should work better. Assuming the folder path you have configured for synchronization in Syncthing is d:\win_apps.

I also deleted 5 files from another folder and that folder also shows out of sync.

Remove folders, restart, add folders resolved the issue.

Sure, it’ll do that, because then the only version Syncthing knows about is the one you have. But you have 14 other devices, any of which apparently could announce a different or newer version of a file. On startup, until those have connected, “no connected device has the required version” is reasonable.

If one of those powered-off devices comes back up and has the deleted file, will it be deleted, or will it be propagated to all other devices?

Generally, deleted, but it depends on whether the deletion is still stored in the other devices’ databases.

If the deletion is present in one of other (powered-on) devices’ databases, it will be synced to the previously powered-off device.

If it isn’t (this would usually happen if there was some database resetting, or if that deletion is older than 6 months), the deleted file will be recreated on the other devices.
