Upgraded from Ubuntu 20 to 22.04.4, Opensnitch UI not opening

[deadbroker]

Hi there

I migrated from Ubuntu 20 to Ubuntu 22.04.4 LTS and Opensnitch doesn't work (version 1.6.5).

I tried opening it from the application launcher in Ubuntu but nothing happens when I click the icon.

I ran $ opensnitch-ui and got the following error:

`Traceback (most recent call last): File "/usr/bin/opensnitch-ui", line 41, in from opensnitch.service import UIService File "/usr/lib/python3/dist-packages/opensnitch/service.py", line 15, in from opensnitch import ui_pb2 File "/usr/lib/python3/dist-packages/opensnitch/ui_pb2.py", line 32, in _descriptor.EnumValueDescriptor( File "/usr/local/lib/python3.10/dist-packages/google/protobuf/descriptor.py", line 914, in new _message.Message._CheckCalledFromGeneratedFile() TypeError: Descriptors cannot be created directly. If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates`

Any clue what's happening here?

I have solved it with the following command:

$ pip install protobuf==3.20.*

I had to downgrade protobuf
