Just wanna mention, if I or anyone else get similar issue because it was kind of frustrating.

This was working up, to a while ago. But then suddenly:

$ docker run -p 6060:6060 --net=scanning --link db:postgres -d --name clair arminc/clair-local-scan:v2.1.6_3bfb31ea61aa42eeb836354976065ccea308707e ; sleep 10

I spent probably half a day chasing the error in the wrong end and eventually I started digging in the specific version being used and updated the image to the latest tag: arminc/clair-local-scan:v2.1.7_5125fde67edee46cb058a3feee7164af9645e07d And it worked.

I have no insight in why it broke, but updating fixed it.

You can close the issue. Br, Jorge

Or I can close it myself.
