GUI crashes on start #524

Closed TamasBarta closed 3 years ago

TamasBarta commented 3 years ago

Hi,

Describe the bug I installed OpenSnitch on Arch Linux to try it, but I can't run the GUI as it crashes on start.

To Reproduce

Steps to reproduce the behavior:

  1. Install https://aur.archlinux.org/packages/opensnitch/ (yay -S opensnitch)
  2. Run the GUI from the terminal

Post error logs: 

$ opensnitch-ui
Traceback (most recent call last):
  File "/usr/bin/opensnitch-ui", line 22, in <module>
    from opensnitch.service import UIService
  File "/usr/lib/python3.9/site-packages/opensnitch/service.py", line 13, in <module>
    from opensnitch import ui_pb2
  File "/usr/lib/python3.9/site-packages/opensnitch/ui_pb2.py", line 22, in <module>
    create_key=_descriptor._internal_create_key,
AttributeError: module 'google.protobuf.descriptor' has no attribute '_internal_create_key'

Expected behavior (optional) A clear and concise description of what you expected to happen.

OS (please complete the following information):

Additional context

Installed packages/versions:

$ pacman -Q python-protobuf python-grpcio python-grpcio-tools opensnitch 
python-protobuf 3.17.3-1

Hi @TamasBarta ,

See if you have an old protobuf version installed via pip: pip3 list | grep protobuf If so remove or upgrade it.

TamasBarta commented 3 years ago

Something must be really messed up, as pip list already crashes. I'll figure out. Until I figure it out, I'll close this issue, as it seems like it is caused by my setup.

thank you @TamasBarta !

@TamasBarta @gustavo-iniguez-goya

I had the same error, on fresh installed ubuntu 20 LTS.

Problems were caused by old python libraries that come with ubuntu

default PyQT5 is 5.14.1 default protobuf is 3.6.1

I had to do a pip install --upgrade of both modules before it worked.

May I suggest that the install procedure on the https://github.com/evilsocket/opensnitch/wiki/Compilation checks the minimum versions of all required packages and upgrades if needed?

Also when you run opensnitch-ui the only thing that appears is a very small icon in the top menu bar. You have to click on that icon to open the UI. The opensnitch-ui itself just gives a short message "connecting to server" or something and it seems it's just hanging. I think this is ment as a background task to start at login time as background process.

Hi @Wouter1 !

Sure, I'll add it soon. I've just downloaded and tested latest ubuntu 20.04.3 and using the dependencies from the repositories the GUI works just fine: python3-grpcio 1.16.1, python3-unicode 1.1.1, python3-slugify 4.0.0 and python3-protobuf 3.6.1.3

Also when you run opensnitch-ui the only thing that appears is a very small icon in the top menu bar. You have to click on that icon to open the UI.

mm, I haven't seen that message "connecting to server". When I click on the systray icon, a dropdown menu shows up, then click on "Events" and the GUI is launched.

Wouter1 commented 2 years ago

Yes. Except that my dropdown looks different, without Events:

I think most users expect a window GUI to pop up immediately when they start a bla.ui application. So I would suggest adding some explanation there in the wiki page.

BTW it works great , many thanks for providing this.

gustavo-iniguez-goya commented 2 years ago

ok, I see. The thing is that that behaviour depends on the Desktop Environment. On Cinnamon, LxQt, KDE and some others, clicking on the systray icon displays the GUI . That's our default behaviour, but some DEs override it.

Ok, I'll add an explanation to the wiki.
