So I think the issue is this Newuidmap failed to write mapping "newuidmap: uid range [1000-1001) -> [1000-1001) not allowed"
Using this configuration:
lxc.idmap = u 0 100000 1000
lxc.idmap = u 1000 1000 1
lxc.idmap = u 1001 101001 64535
lxc.idmap = g 0 100000 1000
lxc.idmap = g 1000 1000 1
lxc.idmap = g 1001 101001 64535
I was able to pass in the “one” user to “ubuntu”.
I also made my subuid and subgid
root:1000:1
root:100000:65536
lxd:100000:65536
Now what I’m not sure about is users two, three and four and that shared group.
