[SOLVED] LXD on Centos 8: lxd init fails after installing from source [Error: Failed to connect to local LXD]

LXD
1

Hello,

I used to have LXD 3.0.4 via snap (on Centos 8), and then I deleted all of it using @stgraber reply here and then installed LXD 3.18 from source.

Now, when I run lxd init , I get this error:

$ lxd init
Error: Failed to connect to local LXD: Get "http://unix.socket/1.0": dial unix /var/lib/lxd/unix.socket: connect: no such file or directory

$ lxd --debug init
DBUG[07-13|20:21:46] Connecting to a local LXD over a Unix socket

Error: Failed to connect to local LXD: Get "http://unix.socket/1.0": dial unix /var/lib/lxd/unix.socket: connect: no such file or directory

However, on running (as root) the following command, it works fine:
# lxd --debug --group lxd

Never mind. It was a silly mistake :slight_smile:
It works fine! I did not realize I was not spawning the daemon properly!

I face the exact same scenario as you described in your initial post (on a Manjaro host. Version : 4.3-1, installed from the standard repositories)

would be great whether you can get a bit into detail on which practical steps are required to "spawn the daemon properly "

nevermind. I found a solution on the manjaro forum

(running: sudo systemctl restart lxd.socket on the LXD host)
