Hey, I encounter an error when trying to create an image from a stopped container or container snapshot. The error message is:
$ lxc publish my-stopped-container --alias my-new-image
...
error: failed to create tar info header: archive/tar: sockets not supported
Should this work? Am I missing something? There’s nothing suspicious/revealing in the debug output.
My lxc/lxd info is:
$ lxc info
config: {}
