[PVE-User] unable to add turnkey container as root

[Adam Weremczuk]

Hi all,

I'm using the latest available:

pve-kernel-4.15                      5.3-3
pve-manager                          5.3-11

etc.

Error log:

I've tried adding permissions under corresponding zfs pool:
Permissions -> Add -> User Permission -> User: root at pam -> Role: 
Administrator
but when I click "Add" nothing appears on the list.

Any ideas?

Regards,
Adam
