Image created with lxc 3.0.3, bzip2 will work on lxc 2.1.1?

Sorry to to ask you again,
if I need to install 2.0.11 on my ubuntu 18.04, what would be my steps

  1. I followed on your other post response for clean up of existing version, so I am good with that ( How to remove LXD from my system). i did a clean of lxc 3.0.3
  2. add-apt-repository << which one to add>>
  3. will this work ?
    apt install lxd=2.0.11
    apt install lxd-client=2.0.11

Best
