NextCloud snap install

I have an Orange PI One.
I installed armbian Ubuntu 16.04.
I installed Snap.d
I wanted to to install Nextcloud snap but it did not work.
Did I do something wrong?
Below is the output of my dealings with it. Thank You for your help.

jwp1@orangepione:~$ sudo snap install nextcloud
error: cannot perform the following tasks:

  • Run configure hook of “nextcloud” snap if present (run hook “configure”: cannot open mount namespace of the init process (O_PATH): No such file or directory)

Can you show us which version of snapd is installed on your system by running:

snap version

jwp1@orangepione:~$ snap version
snap 2.27.5
snapd 2.27.5
series 16
ubuntu 16.04
kernel 3.4.113-sun8i

That looks okayish … are you sure your kernel has all the needed bits enabled for snap support ?
