Reading cache from /usr/local/lib fails with permission denied

[tr4nquillo]

I'm trying to cache C shared libraries, that live in usr/local/lib. Writing the cache is working, but reading from it fails because the action is not able to untar the cache in /usr/local/lib. I wasn't able to find a way to specify permissions for this action, so I'm creating an issue for this.

This is my configuration:

- name: Cache Check Library
  id: cache-libcheck
  uses: actions/cache@v3
  with: 
    path: /usr/local/lib/libcheck.so.0.0.0
    key: ${{ runner.os }}-libcheck

And the error message:

Run actions/cache@v3
  with:
    path: /usr/local/lib/libcheck.so.0.0.0
    key: Linux-libcheck
Received 82079 of 82079 (100.0%), 1.0 MBs/sec

/usr/bin/tar: Exiting with failure status due to previous errors

This is the job setup:

Am I missing anything here or is this really an issue?

Thank you!

@leiferksn if you are using self-hosted runner then please ensure that the runner has access to this file. For GitHub hosted runner, I tried to cache a random file (I did not see /usr/local/lib/libcheck.so.0.0.0 in there) in /usr/local/lib and it worked for me

    - name: Cache Check Library
      id: cache-libcheck
      uses: actions/cache@v3
      with: 
        path: /usr/local/lib/android/sdk/platforms/android-27/data/res/values-bs/strings.xml
        key: ${{ runner.os }}-libcheck

I have the same problem: caching files in /usr/local doesn't work. The error message is the same. @bishal-pdMSFT we should probably reopen this because in your example you cached a file that always exists.

Example build: https://github.com/athenianco/athenian-api/actions/runs/3091205505/jobs/5000988782 (step "cache libsentry")

BTW, this is the workaround. Add the following step before the cache step:

- name: chown /usr/local/lib
  run: sudo chown $(whoami) /usr/local/lib
