Now you can just `sudo snap refresh core --beta` for the 4.18 problem
(tested on 4.18.2 aarch64 from the mainline ppa).

It's always bee the case that a properly configured kernel is needed for
snapd to work. There even have been features added, and bugs fixed, in
the kernel as a direct result of needing features working for snapd (and
in those cases the Ubuntu kernel has often shipped the patches before
they were up
Hmm... I see.

the title is perfectly fine, this bug is about printing a proper error
instead of a cryptic readlinkat() message when there is a kernel in use
that lacks the necessary features (which a proper ubuntu kernel
provides) for snapd to operate correctly. in case there will be 4.18

:-\.
This means snaps render unuseful with these new kernels.
