Extension Manager: exception in synchronize. How can I fix this?

Hallo

It seems there’s something wrong with your Extensions.
search for your LibreOffice-UserConfig-path - on Linux it’s something like:
/home/ <your name> /.config/libreoffice/4/user/
and rename the subfolder uno_packages to backup_uno_packages

try to start LO … good Luck!

I tried changing the subfolder name, but got the same result.

Don’t know whats wrong, but i found an similar Thread
may be the answer helps

found another thread with same problems
