In a 16.04 classic system with the default kernel from linode, snapd 2.0.8 installed (built from https://github.com/snapcore/snapd/commit/71244932e45e05528db6919e23711355d6f63d0c), I get an error when trying to install the first snap, it gets stuck in the last line:

A Linode instance of Ubuntu using the stock Linode kernel does not work with snapd as snapd assumes the ubuntu kernel (when os-release says it is ubuntu) and uses apparmor features otherwise not available.
There are several issues here:
- branding !ubuntu as ubuntu
- running on apparmor system that is not supporting new constructs
- using runtime detection (across snapd+snap-confine) rather than compile-time or simplified (which distro + release) checks |
