host-only network set DHCP error.
I found a few posts with similar problems, but I didn’t find a solution.

VirtualBox 6.1.10
VboxManage 6.1.10r138449
OS Debian 10 (buster)

based on the output of "vboxmanage hostonlyif", with some color added to differentiate []'s:

VBoxManage hostonlyif       ipconfig <name>
                            [--dhcp |
                            --ip<ipv4> [--netmask<ipv4> (def: 255.255.255.0)] |
                            --ipv6<ipv6> [--netmasklengthv6<length> (def: 64)]]
                            create |
                            remove <name>

realigned to be on one line (copy & paste to a text document to see the whole layout):

VBoxManage hostonlyif ipconfig <name> [--dhcp | --ip<ipv4> [--netmask<ipv4> (def: 255.255.255.0)] | --ipv6<ipv6> [--netmasklengthv6<length> (def: 64)]] create | remove <name>

It appears that after "ipconfig <name>", with optional --dhcp, --ip<ipv4>, or --ipv6<ipv6>, there has to be a 'create' or 'remove'.
