Dependabot docker failing with public ghcr.io image

Hello,

I recently started seeing dependabot failing to pull from ghcr.io for a public image. This used to work but seems to have stopped working recently. Package it’s trying to check https://github.com/users/devpow112/packages/container/package/base-ubuntu. The repository trying to run dependabot is private but it should be able to check if it needs updates for a public image. See below log snippet from dependabot logs.

Any help would be appreciated
