permission denied on installing lxd via snap

Question

I'm trying to install LXD on my Ubuntu via this tutorial https://docs.conjure-up.io/devel/en/user-manual#users-of-lxd in it says I have to follow these steps:

1. sudo snap install lxd (no problem in installing)
2. /snap/bin/lxd init (I get the below error)

Error: Failed to connect to local LXD: Get http://unix.socket/1.0: dial unix /var/snap/lxd/common/lxd/unix.socket: connect: permission denied

can anyone tell me how to fix it?

Answer 1

Looks like for some reason the permissions on the unix.socket are not correct. (I tried this myself and works fine). The permission on my unix.socket look like this:

srw-rw----  1 root lxd     0 Nov  7 18:02 unix.socket

I would try:

sudo chown root:lxd /var/snap/lxd/common/lxd/unix.socket
sudo chmod 664 /var/snap/lxd/common/lxd/unix.socket
sudo chmod u+s /var/snap/lxd/common/lxd/unix.socket

If not then it could be an issue with your /var/snap/lxd/common/lxd/ directory. Does it even exist?

Proper way according to Ubuntu page is:

1. sudo apt install lxd
2. sudo lxd init
3. sudo adduser <your-user> lxd
4. newgrp lxd

Now you are ready to launch:

• lxc launch ubuntu:22.04 test
