Hey there! I’ve been using Flox on Mac basically without a hitch for 3 months, and I’ve started to explore using Flox for GitHub Actions. However, I can’t seem to get Flox to activate in a linux environment. Here are the steps I went through.
I wanted to test Flox GitHub actions locally, so I installed act within my Flox environment (GitHub - nektos/act: Run your GitHub Actions locally 🚀)
I then followed the GitHub actions tutorial and set up my workflow like this
name: Flox
on:
workflow_dispatch:
jobs:
build:
name: "Build website"
runs-on: ubuntu-latest
steps:
- name: "Checkout"
uses: "actions/checkout@v4"
- name: "Install Flox"
uses: "flox/install-flox-action@v2"
- name: "Build"
uses: "flox/activate-action@v1"
with:
command: echo "Hello world"
Running this command provides the following output
act -W .github/workflows/ci-v2.yaml workflow_dispatch
INFO[0000] Using docker host 'unix:///var/run/docker.sock', and daemon socket 'unix:///var/run/docker.sock'

I thought this might have to do with me using an Apple Silicon Macbook and running a linux amd64 container using rosetta locally so I tried deploying the action to GitHub to run on one of their runners and it hangs there too, with different logs though (slightly)

Where it hangs after the This is a one-time notice. The “operation was canceled” shows up because I manually quit the workflow after about 15 minutes of no changes.

I took a crash course in Nix but still have a ton to understand but I don’t think I’m doing anything too crazy here.
Any ideas where we can start debugging to figure out the culprit here? I also tried running an Ubuntu machine from Orbstack and that build also froze (but this is essentially a container just like act runs so I guess I’m not surprised this failed as well). Anyways, really appreciate any help and more than happy to provide more resources to help debug. Thanks!!
