What MAAS version are you running?
Can you verify whether there are any errors cropping up in your MAAS logs that might suggest why these services haven’t started?

Can you please also check journalctl -u dhcpd?

7 
$ journalctl -u dhcpd
-- No entries --
$ service dhcpd status
Unit dhcpd.service could not be found.
8

sudo systemctl status maas-dhcpd.service

Perhaps?

There are no services such as ‘isc-dhcp-server’, ‘maas-dhcpd’, ‘dhcpd’…etc.
Nevermind, Finally the problem has been resolved by snap remove maas --purge and then reinstalling MAAS based on the same PostgreSQL database.
