UI does not work in Ubuntu 22.04 (fixed on 23.04) / LinuxMint 21 (temp fix available)

Hi. It's UI bug.

UI app stuck and interface never appear. I see it load my CPU for about 15%.
Tray icon of opensnitch appear as blank area and does not open even menu by click.

I tried to start it from source using cd ui/bin && mv opensnitch-ui opensnitch-ui.py && python3 opensnitch-ui.py and there was some errors with theme module.

I guess it may be somehow related to new libadwaita and that they dropped ability to use user themes.

I don't know how to get you more info. Please tell me how and I will do it.

hey @ergsolo , thank you for reporting this.

What version are you running? gnome, kde?

@gustavo-iniguez-goya
Gnome, Ubuntu 22.04 latest

Actually I told about ubuntu DE
did you ask about version of ui? I thought its qt based only

[gustavo-iniguez-goya]

ok, reproduced. I'll try to find the problem.

[gustavo-iniguez-goya]

ok, the problem seems to be the python3-grpcio version that is shipped with ubuntu 22, 1.30.2-3build6

As a workaround install grpcio version from pip as your regular user: $ pip3 install --ignore-installed grpcio==1.44.0

Note: if it keeps failing (opensnitch-ui is using 100%CPU), be sure that you install it for your python version. for example:

$ python3 -V
Python 3.10.9
$ python3.10 -m pip install --ignore-installed grpcio

@gustavo-iniguez-goya
Thank you, workaround works!

I have the same issue.

I have the same issue since Pop_OS 22.04 (gnome 42) LTS. I tried the $ pip3 install --ignore-installed grpcio and it still does not work. When I launch the sopensnitch-ui pegs one of the CPUs.

[gustavo-iniguez-goya]

I'll take a look , thank you @convolutionbbs

[gustavo-iniguez-goya]

It seems to work fine for me:

Maybe you had it running in backgroud? try killing opensnitch-ui before launching it again.

[convolutionbbs]

Yes, I've tried that. I was launching from the gui icon via Pop_OS. I just tried from the shell:

$ opensnitch-ui
Loading translations: /usr/lib/python3/dist-packages/opensnitch/i18n locale: en_US
None setQuery() exception: int() argument must be a string, a bytes-like object or a real number, not 'QVariant'

and the opensnitch-ui process pegs cpu

[gustavo-iniguez-goya]

mmh, what version are you using? did you install the GUI from sources or using the deb packages?

[convolutionbbs]

Just for fun, I removed all references to opensnitch and opensnitch-ui via dpkg (even using --purge). I was using the x86_64 debian builds for both. I re-installed using Eddy (right click on the .deb file install) using the latest version 1.5.1-1.

python3-opensnitch-ui_1.5.1-1_all.deb
opensnitch_1.5.1-1_amd64.deb

Still get no GUI - pegs CPU. Slightly different otuput - likely because I had an older opensnitch-ui installed when I ran the command before. It's likely not relevant, but I did install: pip install pyasn but it still doesn't find it (maybe there's another version I need).

$ opensnitch-ui
Themes not available. Install qt-material if you want to change GUI's appearance: pip3 install qt-material.
