This is a postsinstall script from greetd deb-package

I think I did it wrong (I took the script from SDDM as a sample)

if ! getent group greeter >/dev/null; then
    addgroup --system greeter
fi

# creating greeter user if he isn't already there
if ! getent passwd greeter >/dev/null; then
    adduser --system --ingroup greeter --home /var/lib/greeter greeter
    usermod -c "minimal and flexible login manager daemon" greeter
    usermod -d "/var/lib/greeter"               greeter
    usermod -g "greeter"                        greeter
    usermod -s "/bin/false"                     greeter
fi

if [ ! -e /var/lib/greeter ]; then
    # If greeter was purged while running, the home dir gets removed but the user
    # remains (as deluser refuses to delete a user that's in use).
    mkdir -p /var/lib/greeter
fi

if [ -d /var/lib/greeter ]; then
    # There has been a -R in version prior to 0.19
    # but this opens up symlink attacks. Remove it.
    chown greeter:greeter /var/lib/greeter
    chmod 0750 /var/lib/greeter
 fi`

Did you create the user for the greeter configured in your configuration file ("greeter" by default)?
