Package 'snapd' has no installation candidate on Linux Mint when wanting to update it

This is after installation using apt-get on my Raspberry Pi 4B running Debian Bookworm:

root@rpi4:/root# apt-cache policy snapd
snapd:
  Installed: 2.57.6-1+b5
  Candidate: 2.57.6-1+b5
  Version table:
 *** 2.57.6-1+b5 500
        500 http://deb.debian.org/debian  bookworm/main arm64 Packages
        100 /var/lib/dpkg/status

and this is the output from my Linux Mint 21.3 Cinnamon:

$ apt-cache policy snapd
snapd:
  Installed: 2.45.1+20.04
  Candidate: (none)
  Version table:

E: Package 'snapd' has no installation candidate

Is there some problem which needs to be addressed on my Mint, or there is some possibly transient error?
