This is the problem I mention after having got the lxd snap up and running under WSL (per post here: Status of LXD on WSL2 ).
The full log is here https://gist.github.com/cerebrate/2591e15dc4e2da0d4964b7b82f9845fc , but the first error it shows is:
lxc deep-macaw 20190709051615.645 ERROR utils - utils.c:safe_mount:1187 - Operation not permitted - Failed to mount "sysfs" onto "/var/snap/lxd/common/lxc//sys"
…and while I’ve found a couple of references to similar errors by searching, neither of them gave me much of a clue as to what the problem might be or how to correct it.
