I have one of my machines where I wanted to remove LXD.
The machine has 2TB SSD, AMD 3900x 12 cores.
Prior to issuing the following command I deleted the 2 containers and 4 LXD VMs .
Then I Issued the following command and its been running now for nearly 30 minutes?
$ sudo snap remove lxd
Save data of snap “lxd” in automatic snapshot set #11
You should make sure to delete all storage pools prior to running snap remove.
Otherwise snapd will make a snapshot of all your data, including the potentially massive sparse file backing your pool.
