Hi @arthurlogilab

Can you provide the associated Dockerfile ?

[arthurzenika]

Hi, I think the following is enough to get reproduce the bug :

FROM debian:buster-slim
LABEL maintainer "Logilab <[email protected]>" \
    org.label-schema.vendor = "Logilab"

[arthurzenika]

Replacing it by

LABEL maintainer="Logilab <[email protected]>"
LABEL org.label-schema.vendor="Logilab"

Seems to fix it, but it would be nice for whale-linter to find this.
