different errors after switching from python 2.7 to 3.6

Vogi

Hello!

I just compiled kopanocore and switched to python 3.6.

Up to now I found two issues:

kopano-search does not start
I get:

Traceback (most recent call last):
  File "/usr/sbin/kopano-search", line 4, in <module>
    import kopano_search
  File "/usr/lib64/python3.6/site-packages/kopano_search/__init__.py", line 17, in <module>
    from Queue import Empty
ModuleNotFoundError: No module named 'Queue'

After changing:

from Queue import Empty

to

from queue import Empty

“init.py” file from kopano search it works.

kopano-presence throws errors:
