The issue is that glibc 2.26 deprecated the "compat" query type of the
Name Service Switch.

We discussed this previously in <https://bugs.gnu.org/30298>.

One can adjust to the change by either using the nscd daemon [0] or
editing /etc/nsswitch.conf and replacing instances of 'compat' with
'files'.

On Debian Stretch, I found that `apt-get install nscd` was sufficient.

I'm going to merge this report with #30298.

[0] We already "strongly recommend" using nscd:
