Lxd version with snap , get 4.4, and show 3.0.3

on fresh ubuntu18.04, i installed lxd with snap.
snap find “lxd” return
lxd version 4.4 from canonical. … FINE!!

so decided to install latest/stable lxd, 4.4
snap install --channel=latest/stable lxd
lxd 4.4 from Canonical✓ installed WOW, DOUBLE FINE!

BUT, when i do lxd version, i get
wtf !
i tried a lot, but lxd version remain always 3.0.3. where is version 4.4 ??
is that normal…?
snap list return
Name Version Rev Tracking Publisher Notes
core 16-2.42.5 8268 latest/stable canonical✓ core
core18 20200724 1885 latest/stable canonical✓ base
lxd 4.4 16926 4.4/stable canonical✓ -
WHY? 4.4 is present , but lxd version always show 3.0.3 !

Ubuntu 18.04 came with LXD 3.0.3 installed as an apt package, whereas LXD 4.4 only comes as a snap package.

To remove the LXD apt package, run lxd.migrate after installing the snap package, which will run through the process of migrating containers and config over to the new version and remove the old one.

If you don’t have a specific reason to be using Ubuntu 18.04, then the latest long term release Ubuntu 20.04 only comes with the snap package of LXD.

yes, perhaps, no tested.
but actually, ovh dont allow to install server with ubuntu20… so i must secure with 18 for the moment…and manage problems…
