[Bug] user in 'docker' group is not detected

[flooryyyy]

What version of WinBoat are you running?

v0.8.7

Your Environment

Distro: NixOS 25.11

❯ groups floory floory : users wheel audio video libvirtd docker input syncthing kvm render rtkit

i don't think any other info matters?

Steps to Reproduce / Context

idk why but i'm getting the following error despite having 'docker' group for ages:

✘ User added to the docker group (Relog required)

all i've done is: downloaded and ran the appimage appimage-run winboat.appimage click next twice until i see "pre-requisite screens

Logs

winboat.log i've managed to install usbutils and restart winboat but it didn't fix it

Expected Behavior

it should show i'm added to the docker group, since i am, and i should be able to proceed.

Current Behavior

it's saying 'x' to the "User added to the docker group" and i can't continue with installing/using winboat

Possible Solution

absolutely no clue

I have this problem, as well. Sorry to not give a solution...

Same issue here. My user is definitely part of the docker group and I create and run other docker containers no problem.

I had the same issue. I found that I needed to fully restart for the user to be detected in the group. Logging in and out did not work for me.

Make sure your adding your current user to the docker group with sudo usermod -aG docker your_user_here

On NixOS you're probably better off installing it using the flake in this repo. I have this issue with the appimage, but not the flake. Probably caused by some quirk with how NixOS runs appimages.

Detecting whether the user is added to the docker group had some issues on nixOS, but afaik it's been fixed in the flake.

You could also try running the app image with the --no-sandbox flag enabled.

I had the same issue but with Arch - both groups $USER and id -Gn $USER would show the docker group but the pre-reqs wouldn't detect it. Restarting PC resolved it, logging in and out multiple times didn't work.

Had the same problem. Restarting the machine worked for me (Ubuntu 24.04).

i'm not sure if my message wasn't clear but i use docker perfectly fine, other apps can use docker containers fine, it's just winboat that isn't detecting it for some reason

i didn't even notice that there's a flake, thanks. i guess i'll leave this issue open since a lot of other people are having same issue too and they're not on nixos

[flooryyyy]

came back to confirm that the flake works perfectly fine, and i'm able to use winboat without any issues. i'm not sure why others experience the same issue on other distributions, though

maybe you need run a reboot cmd

Same issue here, i try with --no-sandbox flag but didn't work.

Also, be nice to fix this problem anyway.

+1, flake works fine tho. https://github.com/TibixDev/winboat/tree/9e4f0b7eb3807e337d4015da126ae52f64c570d3
