You used "su" to become root, I believe. Unfortunately, beginning with Debian 9, "su" with no arguments and no configuration doesn't behave the way it used to behave. Specifically, it no longer sets the PATH variable properly. And so you get the above results. See <https://wiki.debian.org/NewInBuster#Changes> for the options available to you. If you wish to continue using su, I strongly recommend creating a /etc/default/su file.
