Yes, sounds like you’ve configured LXD to use an IP you don’t have on your system.
It’s also hard to tell, but if clustering was ever enabled on this machine, then that’ll be a bit tricky to fixup.
Anyway, easiest way to get LXD running is by adding that IP to your loopback device temporarily:
- sudo ip -4 addr add IP/32 dev lo
Then LXD should start fine, at which point you should update core.https_address to something more relevant. If your IP is likely to change often, then just using :8443 would avoid this issue by always listening on port 8443, regardless of address.
