Synchronizing Linux -> Windows: Merge Failed, Group Signature

[christorrent]

Dear All,

 

on a linux client, there's always the following error message in sync.log:

 

[2014-07-08 14:02:09] Merge: failed to verify group signature of files message, aborting

 

The same share can be synced between two windows machines, but the linux files aren't copied.

 

The error message above is from the windows client!

 

The linux client says

 

Merge: will send files for /datum*
Merge: will send files for /filenames.py*
Merge: will send files for /test*
SyncFolder::ProcessRequest() received non-command request.
State sync finished for folder /home/buero/kindergarten
 

Filenames contain German Umlauts. Is this a problem?

 

It doesn't change anything whether I set the locales with dpkg-reconfigure to en_US.UTF-8 or de_DE.UTF-8.

 

Version is Version 1.3.106 on all clients.

 

Thank you in advance.

 

- Chris

Chris,

 

Your issue is not in the fact that some filenames contain non-latin characters, but in the way they are encoded. The Linux itself does not care about how filenames are encoded - it just works with filenames as with an array of bytes. BTSync expects it to be a UTF-8 characters as it is used to be in Linux.

 

If some app will create files in ASCII - these umlaute chars are going to be invalid from UTF point of view, and as a result will not be able to be synced to Windows machine. 

 

BTW, very simple case which you can encounter is copying files from flash drive formatted to FAT32.

Thank you Roman. We'll change the encoding. Those files were probably created with an old samba version.
