[lxc-users] LXD: error: open /etc/subuid: no such file or directory

[Kunal Kushwaha]

Hi

Thanks for your quick reply.
It has resolved the issue, but now I am facing another issue.


$sudo ./lxd --tcp 10.0.3.1:8888
error: cannot listen on unix socket: listen unix
/var/lib/lxd/unix.socket: bind: address already in use

I confirmed these port are not used, and have tried other ports too.

Regards,
Kunal Kushwaha
