Hey @daghemo a small change, the delete has to be done not with <imageID> but by the tag, then it will work. here’s the exact way of doing that these 4 lines, and the cleanup should succeed:
IMG="$(balena images | grep 'resin/\|balena/' | grep supervisor | grep none | awk '{print $3}')"
REPO="$(balena images | grep 'resin/\|balena/' | grep supervisor | grep none | awk '{print $1}')"
balena tag $IMG $REPO:foobar
balena rmi $REPO:foobar
