Incus Install
$ sudo apt install -t bookworm-backports incus ... Incus has been installed. You must run `sudo incus admin init` to perform the initial configuration of Incus. Be sure to add user(s) to either the 'incus-admin' group for full administrative access or the 'incus' group for restricted access, then have them logout and back in to properly setup their access. ...
Incus Init
$ sudo gpasswd -a bob incus-admin Adding user bob to group incus-admin $ su -l bob $ incus admin init Would you like to use clustering? (yes/no) [default=no]: Do you want to configure a new storage pool? (yes/no) [default=yes]: Name of the new storage pool [default=default]: Name of the storage backend to use (dir, lvm, lvmcluster, btrfs) [default=btrfs]: dir Where should this storage pool store its data? [default=/var/lib/incus/storage-pools/default]: Would you like to create a new local network bridge? (yes/no) [default=yes]: What should the new bridge be called? [default=incusbr0]: What IPv4 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: Would you like the server to be available over the network? (yes/no) [default=no]: Would you like stale cached images to be updated automatically? (yes/no) [default=yes]: Would you like a YAML "init" preseed to be printed? (yes/no) [default=no]:

(yes/no) [default=no]: # yes, create a bridge, which will allow the new envs to access the network Would you like to create a new local network bridge?

much pain and suffering
linuxcontainers.org no longer supports lxd, because Canonical and Mark Shuttleworth are terrible.
Incus is the new open source version of LXD. Coming in Deb 13, backported to Deb 12.

This is exactly why I want virtualization. So when some knob like Mark Shuttleworth screws over the world, I don't have to have his feces smeared all over my hard drive.
