encryption for outgoing messages failed #34

Closed fantomfp closed 3 years ago

fantomfp commented 3 years ago

Hi, I'm having an issue for outgoing messages I use these versions:

This stack can be found for Fedora at https://copr.fedorainfracloud.org/coprs/fantom/poezio-omemo/ When I use python-omemo 0.12.0, it doen't work, but when I used python-omemo 0.11.0, it worked.

I have a traceback in the debug.log file:

2021-04-04 16:09:19,257 ERROR:plugin_e2ee:Exception in encrypt:

    encrypt_for[self.__my_bare_jid].remove(self.__my_device_id)
KeyError: 'jid@jid.jid'

In my config file, I have set a long time ago the device_id

device_id = <random_string_here>

I think the issue is located on the ressource parsing, because the ressource is "jid@jid.com/poezio-[device_id]". Let me know if the problem come from the plugin itself...

Found the solution. When upgrading from python-omemo 0.11.0 to 0.12.0, you need to clear the user data: $ mv .local/share/poezio/omemo ~/ Then it works.
