Try to update snapd and refresh the core snap

When I install the redis-desktop-manager package in debian 10:

error: cannot install snap file: snap “redis-desktop-manager” assumes
unsupported features: snapd2.38 (try to update snapd and refresh the
core snap)

Can anyone help me?

try:

sudo snap install core snapd

(or first snap refresh core and then snap install snapd if core is already installed)

after a reboot snapd should be used from the snapd snap and refresh on a rolling schedule.
