dateutil not found

[garrett]

Running k3x from Flathub on Fedora 32 Silverblue, and I get:

ModuleNotFoundError: No module named 'dateutil'

FWIW: I don't have anything Kubernetes-related on my machine. (Not sure if it's needed or not; from the description, I assumed this should handle everything.)

Hi @garrett. Thanks for reporting this problem. I think I know what happened: the dependency on the dateutil library was missing. I've added it in this commit in the FlatHub repo. The package should be rebuilt in the next hour or so. Please let me know if that fixes your problem.

[garrett]

Indeed, I think that fixes the problem. However, there's a new problem:

Perhaps we should close this and open a new issue though?

I do happen to have Docker installed as an overlay on my Silverblue system, but that's because I do development on Cockpit and have a bunch of things as overlay packages on my work system. (I work as much as I can in a toolbox container and in Flatpaks too, but some things need to be RPM overlays directly on the system if I don't want to have to build and run a VM for everything.)

Since this issue seems to be fixed, but there are other issues, I've opened more issues and am closing this one:

1. When there's an error like this, it should open a window with the error instead of "doing nothing" if you run the app from the UI. Display errors in a graphical way #14
2. Does k3x work with podman? Podman support? #15
3. Can k3x work on Silverblue? Fedora Silverblue support? #16

Im running into the same issue (2nd one) and running non-silverblue Fedora 32. I thought it was due to moby-engine instead of docker, but I got docker working (aka docker ps returns containers), and still facing the issue.

k3d create cluster command works.

[garrett]

@smazurov: I think the issue is related to cgroups v2 and Docker (Moby) not supporting it properly. Can you run a Docker container on your system with sudo docker run -it alpine cat /etc/os-release ?

It should show things like PRETTY_NAME="Alpine Linux v3.12" and such if it works. Alpine is super-lightweight and a different distro, hence my suggestion on trying it.

If it doesn't work, is it related to cgroups v2? You'd probably see a similar error message as the third one in this comment on the Silverblue issue: #16 (comment)

The best solution would probably be to support podman (#15) and forget about Docker cgroups v2 support.

[inercia]

@smazurov if k3d create cluster command works, could you try running k3x in a terminal with flatpak run --user com.github.inercia.k3x and get the debug logs? I would like to take a look at the logs for debugging the issue.

[smazurov]

Error log is in the second message in this thread. My docker works and I enabled old cgroups

[smazurov]

Here's the log:
