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

[ghost]

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.

[gustavo-iniguez-goya]

hey @ergsolo , thank you for reporting this.

What version are you running? gnome, kde?

[ghost]

@gustavo-iniguez-goya
Gnome, Ubuntu 22.04 latest

[ghost]

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

[ghost]

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

[Ahmed-E-86]

I have the same issue.

[convolutionbbs]

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.
Loading translations: /usr/lib/python3/dist-packages/opensnitch/i18n locale: en_US
exception loading ipasn db: No module named 'pyasn'
Install python3-pyasn to display IP's network name.

[gustavo-iniguez-goya]

ok, the previous error exception: int() looked suspicious, that's why asked you for the version :)

Unfortunately I have no idea why it's not working on your system :/
Try uninstalling python3-grpcio, it'll also remove python3-opensnitch-ui. Then install this deb package without the python3-grpcio dependency: https://github.com/evilsocket/opensnitch/releases/download/v1.5.1/python3-opensnitch-ui_1.5.1-1_all.PIP.deb

Regarding the pyasn package: installing it from pip doesn't install the needed DB, no idea why. On Pop_OS the package is available from apt: apt install python3-pyasn

[convolutionbbs]

that did it - thanks!

[gustavo-iniguez-goya]

After rebuilding our grpcio files with latest grpcio version, this problem is fixed for Ubuntu 22 and derivatives.
I'll test it out on the rest of versions and distributions, and if everything works fine I'll rebuild the GUI packages.

nah, false alarm.

[convolutionbbs]

Just wanted to say thank you for your support of this great project - the ease of use and capability is outstanding.

[gustavo-iniguez-goya]

I opened a bug report with Ubuntu detailing the steps to reproduce this problem . Hopefully they'll reproduce the same behaviour. A simple grpcio example fails as well:

https://bugs.launchpad.net/ubuntu/+source/grpc/+bug/1971114

[impredicative]

Requirements have always been a major thorn for this project, and seem like they will continue to plague this project, disallowing it from being too successful. Any modern project would be fully compiled or packaged without a single one of these unbundled requirements. These days standalone various packagers exist even for Python, so I don't know what the hangup is.

---

To summarize, here are the extras that I had to run to get the v1.5.1-1 UI running on Ubuntu 22.04:

sudo apt install python3-pip python3-pyasn
pip3 install --user qt-material
pip3 install --user --ignore-installed grpcio

I think python3-pyasn could be documented in the Installation page, or otherwise it could perhaps be installed automatically.

[gustavo-iniguez-goya]

Hi @impredicative , nor python3-pyasn, nor qt-material are mandatories. The GUI works just fine without them. Otherwise file a bug specifying what's wrong.

The problematic requirements have always been grpcio, unicode_slugify and protobuf, because they were not shipped with many distributions (min18/19, ubuntu <= 18, etc). And now, there's a bug with python3-grpcio.

The deb/rpm packages has worked flawlessly until now, just with apt -f install ./python3-opensnitch-ui**.deb ./opensnitch*.deb

On the other hand, the workaround to this specific problem was documented here #647 (comment) more than 1 month ago.

I also filed a bug for the python3-grpcio problem here https://bugs.launchpad.net/ubuntu/+source/grpc/+bug/1971114 where you can drop a comment to let them know that this problem affects you. This bug also affects warpinator (mint 22.04): linuxmint/warpinator#127

[g3434343]

I can confirm it works for me in Pop-Os! 22.04.

[BillDietrich]

Recently the UI stopped working on openSUSE Tumbleweed KDE. Running opensnitch-ui on CLI gives "ModuleNotFoundError: No module named 'grpc'". "zypper search grpc" says the only grpc thing installed is "python38-grpcio".

Tried doing "pip3 install --user --ignore-installed grpcio", and now running opensnitch-ui on CLI gives "ModuleNotFoundError: No module named 'google'".

[gustavo-iniguez-goya]

@BillDietrich that's weird, maybe an upgrade uninstalled the package python3-grpcio? but it'd have also uninstalled the GUI.. so, no idea.

You also need protobuf to solve the error "No module named google": $ sudo zypper install python3-protobuf (or with pip: $ pip3 install protobuf

But anyway, try to install both python3-grpcio and python3-protobuf from SuSe's repositories.

[temporarium]

Just to inform, since I recently had issues with the UI on openSUSE Tumbleweed as well: it appears the system Python was changed from 3.8 to 3.10. As a result, I had to zypper install the corresponding (python310) modules of grpcio, protobuff and slugify.

Now it's working normally.

[gustavo-iniguez-goya]

Thank you very much @temporarium ! @BillDietrich , it looks like that's also the problem on your case.

[temporarium]

No, thank you @gustavo-iniguez-goya for an excellent application and all the hard work!!

[erdnaxeli]

Just to let you know that this issue also impact Fedora 36. I had to install those python packages :

• grcpio
• protobuf==3.15.8
• slugify
• unicode

[Flimm]

The same issue exists in Ubuntu 22.10, and it seems like the same solution works.

sudo apt install python3-pip
pip3 install --ignore-installed --user grpcio==1.44.0

[gustavo-iniguez-goya]

Thank you @Flimm ,

The bug is still opened and without feedback: https://bugs.launchpad.net/ubuntu/+source/grpc/+bug/1971114
I don't know if the link "this bug affects me too" would make any difference: https://bugs.launchpad.net/ubuntu/+source/grpc/+bug/1971114/+affectsmetoo

Given that a basic example doesn't work either, this must be affecting all projects that use this package.

[gustavo-iniguez-goya]

I realized yesterday that the opensnitch-ui process was consuming 6% of the CPU doing nothing. It turns out that it's a bug in the grpc lib:
grpc/grpc#30428

Installing grpcio==1.44.0 solves this problem: $ pip3 install --user --ignore-installed grpcio==1.44.0

[temporarium]

Which are the buggy versions? Mine is v1.51.1 and CPU load is 0.

[gustavo-iniguez-goya]

it seems to be >= 1.45.0 and < 1.48

[IrIougER]

Solved the issue on Mint 21 thanks.

[wp-coin]

why is he using python for the gui, even electron will be better

[MikeGrace]

Thank you. The workaround resolved my issue running Ubuntu 22.04.1 LTS.

[burritoOverflow]

Carelessly installed a grpc related update on Ubuntu 22.04 and broke it--the following worked for me:

 pip3 install --ignore-installed grpcio==1.44.0

Note: I had to manually kill the opensnitch-ui process and re-launch for it to work again.

Thanks!

[Ileca]

I lost the interface when upgrading to Ubuntu 22.10 and got it back by doing pip3 install --ignore-installed grpcio==1.44.0 but now I have a version mismatch error about me running the 1.6.0rc5 version of the daemon while the UI is at version 1.5.0rc2. And it makes OpenSnitch bugs indeed as I installed that app spamming connections but it still ask me for permission for every new website even after I allowed the executable. I tried to look at the rules but the UI finally crashed.

[gustavo-iniguez-goya]

@Ileca , grpcio version should not affect installed opensnitch version. Open a new issue or Discussion question, but be sure your packages versions are correct (dpkg -l | grep opensnitch) . It looks like you upgraded the daemon, but no the GUI.

[Ileca]

Yeah, that's completely on me. Forget what I said, I will crawl into a hole now.

[vibescartel1]

Daemon runs but attempting to run opensnitch-ui gives the following error on Ubuntu 22.04:

Traceback (most recent call last):

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).

I seem to have all the required packages installed, but version might be causing issues?

python3.10 -m pip install grpcio protobuf slugify

[nettybun]

@vibescartel1 You need 3.20.x or lower, as said in the error message. I got the same error and fixed it like this:

python3.10 -m pip uninstall protobuf

Do you mean Ubuntu 23.04, the Ubuntu version that was just released?

[snivlle]

I realized yesterday that the opensnitch-ui process was consuming 6% of the CPU doing nothing. It turns out that it's a bug in the grpc lib: grpc/grpc#30428

Thanks very much! This worked for me on Kubuntu 22.04.2.
I had been really, really wanting an application-level firewall and "OpenSnitch" fits the bill perfectly. I sincerely hope that you can get it all sorted out so that it is regularly bundled into the official Ubuntu (and variants) releases. I'm very far removed from being a qualified, experienced Linux user - I'm still very much learning. I'm sure that there are many thousands upon thousands more like me. As such, it would be so HUGELY appreciated if the program could be a wee bit more easily installed -- without having to muddle about with CLI commands that I have absolutely no idea are actually doing to my system . . .LOL.

Thanks so much for all your hard work and efforts in maintaining this all-too-important Linux application! I am totally surprised that such a commonly used type of app (within both Windows and OSX) hasn't long since been 'built in' to most Linux distributions. Another sorely lacking net app is something similar to **NetLimiter", which I rely on a great deal within Windows to manage bandwidth (both globally and per application).

[gustavo-iniguez-goya]

Thank you @snivlle for the kind words, truly appreciated.

Thanks to Peter Reinholdtsen finally opensnitch is in Debian 12, and due to this it'll also be available on Ubuntu 23.04:
https://packages.ubuntu.com/lunar/opensnitch
https://packages.ubuntu.com/lunar/python3-opensnitch-ui

But besides this, we'll no longer have this issue with grpcio/protobuf on Ubuntu 23.x (we'll have others....), it seems to be fixed with the new packages uploaded.

[impredicative]

@gustavo-iniguez-goya For what it's worth, Nuitka is a well-known Python "compiler". Of course there is more to packaging opensnitch than just the Python bits, but something like Nuitka could handle all the Python bits.

[gustavo-iniguez-goya]

That's interesting @impredicative , thank you!

[B4rabbas]

Hello, open snitch don't work, even with the workaround here on Linux Mint 21.3 x86_64.

[Lynx-Express]

Installing grpcio==1.44.0 solves this problem: $ pip3 install --user --ignore-installed grpcio==1.44.0

Fixed "GUI not showing up" -problem in Pop!_OS 22.04. Thanks.
