*** END OF BUG DESCRIPTION ***

chris@CKR-2:~$ lsb_release -rd
Description: Ubuntu 15.10
Release: 15.10

chris@CKR-2:~$ apt-cache policy x11-utils
x11-utils:
  Installed: 7.7+3
  Candidate: 7.7+3
  Version table:
 *** 7.7+3 0
        500 http://us.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages
        100 /var/lib/dpkg/status

I expected the installation of x11-utils to pull _all_ required dependencies to avoid spurious errors/outputs.

I had to hunt down a 10-year-old bug-report on this same issue, which was more of a work-a-round for another package, than the fix truly needed. See: https://bugs.launchpad.net/ubuntu/+source/xterm/+bug/67435

BTW: This is on a minimal ubuntu-server install without: xterm or x11-apps
