miniconda install fails on self hosted runner

[GeorgWa]

I have a new windows 10 installation which I would like to use for performance tests with a custom github actions runner.
Unfortunately, the miniconda installation fails as, to my understanding, the installation cannot be found.

I used a very simple action:

name: performance testing

on: 
  workflow_dispatch:

env:
  TEST_DATA_DIR: ../_data/

jobs:
  loose_installation:
    name: Performance testing
    runs-on: self-hosted
    
    steps:
      - uses: actions/checkout@v3
      - uses: conda-incubator/setup-miniconda@v2
        with:
          miniconda-version: "latest"
      - name: Conda info
        run: |
          conda info

When run, the conda-incubator/setup-miniconda@v2 fails with the following error:

No installed conda 'base' environment found at 3!If you are using this action in a self-hosted runner that already provides its own Miniconda installation, please specify its location with a `CONDA` environment variable. If you want us to download and install Miniconda or Miniforge for you, add `miniconda-version: "latest"` or `miniforge-version: "latest"`, respectively, to the parameters for this action.

For some reason the instalation path is set to /D=3 although C:\Windows\ServiceProfiles\NetworkService\miniconda3 is used during miniconda installation. Please let me know if you need more information or logs.

Workaround for future reference for users which encounter the same error:

Initially I decided to run the self hosted runner as a service which executed code as NT AUTHORITY\NETWORK SERVICE user. Instead, I now use an already existing account and installed conda manually which works fine.

Nevertheless, having a workflow which install conda automatically my setup-miniconda would be great!

Hi @GeorgWa thanks for reporting the issue. We still have not properly set testing for self hosted runners, and without more details of your exact environment we cannot fully debug this.

If you can provide what your setup is and the system details, we can take a look at it when setting up testing on a self hosted runner.

Cheers!
