I'm trying to create a Prometheus Exporter for our snap store metrics. At first I tried installing snapcraft in a docker container myself using apt-get, but that kept hanging during build while trying to contact the snapcraft store. So I switched to using the snapcore/snapcraft docker container, but the version of snapcraft included in those images is a few versions out of date (all channels seem to be in the 4.4.x-4.6.x range). I found a related issue https://bugs.launchpad.net/snapcraft/+bug/1639112, but that one was closed because some automation was added to keep the images up to date. If that is the case, it seems like that automation may be broken.
