Steps to reproduce the error

I'm just trying to move Offlineimap configuration to the new server, but I have such error as above. I don't know how to troubleshoot this because I do not have anything in log.

Please post back with output from:
python --version

root@offlineimap:~# python --version
Python 2.7.18rc1

1. Could you try to git bisect this? http://offlineimap.org/doc/git-bisect.html

2. Also, what's your configuration file? Note: Redact/remove private info such as server addresses and passwords.

--dry-run mode is known to have issues. Do you hit this without this option?

[zuku81]

without --dry-run I have the same error:

I've edited the posts as requested.

[zuku81]

OK, I just commented these lines in .offlineimap.py

#from offlineimap import OfflineImap
#oi = OfflineImap()
#oi.run()

and my offlineimap is working now ;)
