Comment 4 for bug 1957123

This bug was fixed in the package livecd-rootfs - 2.664.37

---------------
livecd-rootfs (2.664.37) focal; urgency=medium

  * Do not look for a base snap on snaps of type base, because recursive
    dependencies are not allowed for snaps. LP: #1957123.
  * Treat it as a fatal error if we are asked to install a snap that would
    pull in the core snap. Ubuntu 20.04 and Ubuntu 22.04 official images
    should never require snaps that depend on an Ubuntu 16.04 runtime, this
    indicates a misconfiguration that will bloat the install.
