yes, I am using docker - but container must be privileged for docker
to run properly.

it is clearly described on:

I have the same issue.

It's really strange, today I am not able to launch any installation,

$ lxc launch ubuntu: test
Creating test
error: Couldn't find the requested image

It looks like aliases got lost on  https://cloud-images.ubuntu.com/releases ?

$ lxc image list ubuntu:

++--++-+-+--+---+
|   ALIAS| FINGERPRINT  | PUBLIC |
DESCRIPTION   |  ARCH   |   SIZE   |  UPLOAD

What is "p (5 more)"?

Did I miss something?

You put too much into the network-config file, remove "network":

What is a sense of using ZFS if you don't use its cache? Non sense. it
will work slower and less reliable than ext4.

With 1GB of memory is is not recommended to use ZFS not BTRFS,
especially via a disk image file. Just forget about it.

I would not appreciate something which "automatically" (whatever it
means) traverse my firewalls, to be honest. We should treat our data

I think you must read more, because everything you wrote is simply false.

Or, maybe, try it? :-) :-) :-)
