I edited your post so that the output is easier to read. See here for instructions on how I did it.
I can see that you have partially configured LXD (Deb package). The last command, lxc profile show default, shows that the network has been configured, but there is no storage disk/pool. That is, you cannot create containers if there is no storage.
It is not clear why there is no storage. Was there storage before? Did you have containers before? Did you try to lxd.migrate at any point?
If you can revert from a backup, it would be easier to figure out what is going on.
What is needed, is a working system.
Decide whether you want to keep the LXD DEB installation, or whether you want to migrate to the LXD snap package.
