opensnitch-ui (<= 1.6.0rc4-1.noarch) needs protobuf package to 3.20.x or lower

[iolpltuisciaoln]

opensnitch-ui-1.5.2-1.noarch.rpm as well as opensnitch-ui-1.6.0rc4-1.noarch.f29.rpm not starting after Fedora upgrade to 37

To Reproduce
Linux localhost.localdomain 6.1.13-200.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Feb 22 17:53:57 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

rpm -i opensnitch-ui-1.6.0rc4-1.noarch.f29.rpm

TypeError: Descriptors cannot not 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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

Hi @iolpltuisciaoln ,

Could launch the GUI from a terminal as follow?:
$ PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python opensnitch-ui

Let me know please if the GUI show up.

[iolpltuisciaoln]

Yes GUI starts this way after about a minute.

[gustavo-iniguez-goya]

thank you @iolpltuisciaoln !

I'll try to reproduce it and find a solution. I've got an idea.

[gustavo-iniguez-goya]

@iolpltuisciaoln , could you post info of your packages python3-grpcio and python3-protobuf?
$ yum info python3-grpcio python3-protobuf

I've just installed it on Fedora 38 beta and it doesn't crash. Maybe this crash is caused by a specific version of protobuf/grpcio.

Fedora 38 versions: python3-grpcio 1.48.3, python3-protobuf 3.19.6

thank you @iolpltuisciaoln , I'll regenerate the protobuffers with 3.19.0 and will post them here for you to test them (in 8h more or less...)

[gustavo-iniguez-goya]

I'm unable to reproduce this issue 👎 and the current protobuffers seems to be generated with v3.20.0, so for now you'll have to use the above workaround, well adding it to your ~/.bashrc well adding it to your /etc/environment file.

By the way, regarding the delay showing up the GUI, you'll need to install and enable the extension gnome-shell-extension-appindicator: https://github.com/evilsocket/opensnitch/wiki/Known-problems#opensnitch-icon-does-not-show-up-on-gnome-shell

[iolpltuisciaoln]

partially fixed with
pip3 uninstall protobuf
starting is slow tho, gnome-shell-extension-appindicato and python3-notify2 are installed.
probably fc37 issue
