Github action - ##[error]File not found: 'tar'

Question

whenever I run using runs-on: self-hosted it always return an below error but there is no error if I run using runs-on: ubuntu-latest.

on:
  push:
jobs:
  test:
    runs-on: self-hosted
    steps:
      - uses: actions/checkout@v2
      - name: Run tests
        run: |
          echo hi

This machine is using CentOS Linux 7 (Core) - Architecture: x86-64 and for this job, I have created new user called github. Is this because this user cannot access this /usr/bin/tar when running from workflow file?

Answer 1

I faced the same error message. The problem seemed that the action runner directory had a empty .path file. So, I guess it used this to set the path, which effectively removed all path. My solution was to remove the empty .path file
