How to install lxd 2.9 in ubuntu 16.04.2?

Question

https://linuxcontainers.org/lxd/news/ says the latest version of lxd is 2.9.1, as of 16th February 2017.

I just installed ubuntu 16.04.2 and did

sudo apt install lxd

And I have

$ lxc --version
2.0.9

How do I update to 2.9.1?

Answer 1

To get the latest upstream release, a PPA is available:

add-apt-repository ppa:ubuntu-lxc/lxd-stable
apt-get update
apt-get dist-upgrade
apt-get install lxd

(Arrogantly copied from the docs)

Answer 2

The one way that I know is to first uninstall lxd then reinstall it using snap:

Here is the steps:

sudo apt remove lxd lxd-client
sudo snap install lxd

Then you can proceed with the configuration part:

lxd init

But what I am trying to find out if there is any way at all that I can upgrade it without uninstalling...
