LXD is a system container manager
With LXD you can run hundreds of containers of a variety of Linux distributions, apply resource limits, pass in directories, USB devices or GPUs and setup any network and storage you want.
LXD containers are lightweight, secure by default and a great alternative to running Linux virtual machines.
Run any Linux distribution you want
Pre-made images are available for Ubuntu, Alpine Linux, ArchLinux, CentOS, Debian, Fedora, Gentoo, OpenSUSE and more.
A full list of available images can be found here: https://images.linuxcontainers.org
Can't find the distribution you want? It's easy to make your own images too, either using our distrobuilder tool or by assembling your own image tarball by hand.
Containers at scale
LXD is network aware and all interactions go through a simple REST API, making it possible to remotely interact with containers on remote systems, copying and moving them as you wish.
Want to go big? LXD also has built-in clustering support, letting you turn dozens of servers into one big LXD server.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Linux Mint 18.2 (Sonya), Linux Mint 18.3 (Sylvia), Linux Mint 19 (Tara), Linux Mint 19.1 (Tessa) and the latest release, Linux Mint 20 (Ulyana). You can find out which version of Linux Mint you’re running by opening System info from the Preferences menu.
On Linux Mint 20, /etc/apt/preferences.d/nosnap.pref needs to be removed before Snap can be installed. This can be accomplished from the command line:
sudo rm /etc/apt/preferences.d/nosnap.pref
sudo apt update
To install snap from the Software Manager application, search for snapd and click Install. Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either restart your machine, or log out and in again, to complete the installation.
To install LXD, simply use the following command:
Browse and find snaps from the convenience of your desktop using the snap store snap.
