Random 403 errors when pushing to GHCR

Troubleshooting

Pushing to GHCR seems to randomly resulting in 403s in the last 24 hours. Rerunning the GH action seems to resolve things (partially).

Behaviour

See above.

Failure message : buildx failed with: error: failed to solve: unexpected status: 403 Forbidden

Steps to reproduce this issue

1. Kick off GH action to rebuild Docker images
2. See https://github.com/jauderho/dockerfiles/actions
3. Check one of the recent failed runs. For example, https://github.com/jauderho/dockerfiles/actions/runs/1255324536

Expected behaviour

Builds should complete with no issue.

Actual behaviour

[onedr0p]

After a couple more hours of debugging I fixed it with this under the package settings, or the problem resolved itself.

It doesn’t make sense why this would be needed for one image package in my repo and not the other image packages in the same repo.

You can find it in https://github.com/orgs/[XXX]/packages/container/[YYY]/settings

or by going to the package page then “package settings”
