Offlineimap not working after big update

[Sasha]

Hi,

Since the last (big) update, I have some troubles to make offlineimap working.
I read this Offlineimap throwing error now - #6 by mithrial but it doesn’t apply to me, I think.
I have offlineimap 8.0.0-1 installed.
I have python versions 2 and 3.

Here is the traceback. Is this about a python error?
Thanks.

ERROR: Exceptions occurred during the run!
ERROR: While attempting to sync account 'myaccount'

Press any key to continue...

From the stacktrace, the error is in your /home/alex/.offlineimap.py script which I believe at some point was defined by you?
Since offlineimap 8.0.0, it’s using Python 3, so you have to adjust your script to the new version.

Thanks!!
For the record, I changed my .offlineimap.py.
It was written following OfflineIMAP - ArchWiki (section Uging gpg).
I changed:

def get_pass():
    return check_output("gpg -dq ~/.offlineimappass.gpg", shell=True).strip("\n")

by

def get_pass():
    return check_output("gpg -dq ~/.offlineimappass.gpg", shell=True).splitlines()[0]

and it works.
