[SOLVED] Seafile pro docker - problem syncing libraries created with ENCRYPTED_LIBRARY_VERSION = 3

I’ve just installed a new server pro (demo mode) with docker. version is 7.1.6

I’ve added
ENCRYPTED_LIBRARY_VERSION = 3 in
/opt/seafile-data/seafile/conf/seahub_settings.py

If I create a new library I can create and open the library from the web interface and browse it both from client and web it’s fine.

If I try to sync it I got this error : screenshot_2020-08-07_10-24-37

If I comment out the line in seahub_settings it works fine , but I suppose it uses the old library format (and I prefer to go 3.0)

client :
seafile-gui 7.0.6-1 under ubuntu 20.04

updated seafile-gui to 7.0.9 and now it works
