Can't follow symlinks: ENOENT: no such file or directory, lstat 'filename' about ghaction-github-pages

Symlinks do indeed work on gh-pages

Yes we can use symlinks on GitHub Pages but in some cases link target is not available or is based on an absolute path which cannot be resolved on the target branch.

@ranisalt

To me it was easy, I just use cp with the flag to copy the file when a symlink is encountered

Thanks for pointing this out. I think we could mitigate this behavior here. I will take a look and keep you in touch.

Meanwhile, if that's not trivial to solve, I can run something like this:

for f in ${{ env.PKGDEST }}/*; do
  if [ -L "$f" ]; then
    rp=$(realpath "$f")
    unlink "$f"
    cp "$rp" "$f"
  fi
done

To get rid of the symbolic links

@ranisalt I think it's linked to permissions issues on these files and your whole workflow where you tamper the GitHub Runner with your builduser user. Fyi, the standard user in the GitHub Runner is already sudoer. You can try to recover permissions on pkgs folder with sudo chown -R $(id -u):$(id -g) ./pkgs before the GitHub Pages step.

@crazy-max this action runs as root, it should not have any permission issues, but I will try that nevertheless

[ranisalt]

No luck. Still the same problem, even with all files owned by root (id -u and id -g)

- run: chown -R $(id -u):$(id -g) ${{ env.PKGDEST }}

should be:

- run: sudo chown -R $(id -u):$(id -g) ${{ env.PKGDEST }}

[ranisalt]

The action already runs as superuser. It is clear that the owner and group have been updated. id -u and id -g return root.

I've just bumped into this issue after encountering the same problem. Symlinks do indeed work on gh-pages and can be quite useful (e.g to create an index.html that directs to another page).

The PR referenced above is trying to get a bunch of automatically generated symlinks pushed to gh-pages for this exact use case. Such a workflow was used successfully on Travis until we had to migrate to Github Actions.

I'll try fiddling with file ownership as suggeted above to see if I can get it working. Meanwhile any suggestions about how to address this issue would be appreciated!

[ranisalt]

@jlstevens there are no issues with the ownership, it changes nothing. You have to replace links with the actual files instead.

To me it was easy, I just use cp with the flag to copy the file when a symlink is encountered: https://github.com/ranisalt/rsaur/blob/825cf272159798d3d616f6fed8b241ce686bf7f4/.github/workflows/repo.yml#L56 where ${{ env.PKGDEST }} is where the files are, and output is where they will be copied into (the build_dir for this action)
