Please see this url:
Click on “alpine” (This is a public image), but upon clicking, it is displaying a 404 page and prompting to login (url: https://github.com/users/kcak11/packages/container/package/alpine)
However if trying to pull the image from command line like anonymously:
docker pull ghcr.io/kcak11/alpine:3.13
Then I am able to pull the image.
So, the issue is with the Github UI i.e. “Packages” tab not allowing the user to view the details of a public image.
This was working fine 2-3 days back, so something changed very recently.
