The bug is in the file /opt/zextras/common/lib/jylibs/state.py in 2 places, here is the patch:

But after you fix this, the next error is: Postconf error ('ascii' codec can't decode byte 0xc2 in position 16: ordinal not in range(128))

This is caused by the execution of postconf in a UTF-8 environment. The fix is to add the following lines to the file /etc/systemd/system/carbonio-appserver.target.wants/carbonio-configd.service:
