  LXD is a system container and virtual machine manager.

  It offers a simple CLI and REST API to manage local or remote instances,
  uses an image based workflow and support for a variety of advanced features.

  Images are available for all Ubuntu releases and architectures as well
  as for a wide number of other Linux distributions. Existing
  integrations with many deployment and operation tools, makes it work
  just like a public cloud, except everything is under your control.

  LXD containers are lightweight, secure by default and a great
  alternative to virtual machines when running Linux on Linux.

  LXD virtual machines are modern and secure, using UEFI and secure-boot
  by default and a great choice when a different kernel or operating
  system is needed.

  With clustering, up to 50 LXD servers can be easily joined and managed
  together with the same tools and APIs and without needing any external
  dependencies.

  Supported configuration options for the snap (snap set lxd [<key>=<value>...]):

    - ceph.builtin: Use snap-specific Ceph configuration [default=false]
    - ceph.external: Use the system's ceph tools (ignores ceph.builtin) [default=false]
    - criu.enable: Enable experimental live-migration support [default=false]
    - daemon.debug: Increase logging to debug level [default=false]
    - daemon.group: Set group of users that have full control over LXD [default=lxd]
    - daemon.user.group: Set group of users that have restricted LXD access [default=lxd]
    - daemon.preseed: Pass a YAML configuration to `lxd init` on initial start
    - daemon.syslog: Send LXD log events to syslog [default=false]
    - daemon.verbose: Increase logging to verbose level [default=false]
    - lvm.external: Use the system's LVM tools [default=false]
    - lxcfs.pidfd: Start per-container process tracking [default=false]
    - lxcfs.loadavg: Start tracking per-container load average [default=false]
    - lxcfs.cfs: Consider CPU shares for CPU usage [default=false]
    - lxcfs.debug: Increase logging to debug level [default=false]
    - openvswitch.builtin: Run a snap-specific OVS daemon [default=false]
    - openvswitch.external: Use the system's OVS tools (ignores openvswitch.builtin) [default=false]
    - ovn.builtin: Use snap-specific OVN configuration [default=false]
    - ui.enable: Enable the web interface [default=false]

  For system-wide configuration of the CLI, place your configuration in
  /var/snap/lxd/common/global-conf/ (config.yml and servercerts)
commands:
  - lxd.buginfo
  - lxd.check-kernel
  - lxd.lxc
  - lxd
services:
  lxd.activate:    oneshot, enabled, inactive
  lxd.daemon:      simple, enabled, inactive

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

Status in lxd-installer package in Ubuntu:
  New

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
