More searching in the output of "journalctl -xe" turns up:
debm NetworkManager[583]: /usr/sbin/NetworkManager: error while loading
shared libraries: libjansson.so.4: cannot open shared object file: No
such file or directory
In another (non-minimal) system with a working DNS:
root@debU:~# apt search libjansson
[snip]
libjansson4/stable,now 2.9-1 amd64 [installed,automatic]
C library for encoding, decoding and manipulating JSON data
Says it's installed but where? Running "whereis" turns up nothing.
