Unclear messages

What do I have to understand under the following messages?

$ deckschrubber -registry "${REGISTRY}" -latest 1 -repo itbh/hopon-fahrplan -repos 999 -dry
...

A quick grep reveals the answer:

grep -nHRi 'Could not fetch tag!' -B 5 -A 5 .
Binary file ./deckschrubber matches
./main.go-159-			}
./main.go-160-
./main.go-161-			tagLogger.Debug("Fetching tag...")
./main.go-162-			desc, err := tagsService.Get(ctx, tag)
./main.go-163-			if err != nil {
./main.go:164:				tagLogger.Error("Could not fetch tag!")
./main.go-165-				continue
./main.go-166-			}
./main.go-167-
./main.go-168-			tagLogger.Debug("Fetching manifest...")
./main.go-169-			mnfst, err := manifestService.Get(ctx, desc.Digest)

We use the Docker API and from here on it can be anything from mismatching API versions to network problems. I think what you are proposing is to forward messages from Docker API.

I'll keep this open as a reminder to printout errors from Docker API. Thanks for the comment.
