What happens when you type:

$ snap info core

Also, what happens when you type:

$ snap refresh

Yes.

On an Ubuntu Core system snapd is integral to the device, on a classic system
snapd is an add-on package so in the former case the system and snapd are
updated together.

ubuntu-core is the old name for core. We renamed this to better reflect that
other cores could be available that are not Ubuntu based. Do you have both of
these installed on your system? In fact, can you give us a full output of:

$ snap list
