[Bug 2061017] Re: lxd-installer: permission error not handled and lxd snap not installed

[Simon Déziel]

The problem is not with a Raspberry Pi as that works fine:

The problem seems to be when the invoking user is not a member of the `lxd` group which is why there is a Permission denied.

Title:
  lxd-installer: permission error not handled and lxd snap not installed

Status in lxd-installer package in Ubuntu:
  Confirmed

Bug description:
  On a fresh install of 24.04 server on Raspberry Pi, I ran 'lxc list'
  without having the lxd snap installed already. There was an attempt to
  install the snap, but it failed, and the snap needed to be manually
  installed:

  nr at pi5:~$ lxc list
  Installing LXD snap, please be patient.
  Traceback (most recent call last):
    File "<string>", line 1, in <module>
  PermissionError: [Errno 13] Permission denied
  /usr/sbin/lxc: 12: exec: /snap/bin/lxc: not found
