Status changed to 'Confirmed' because the bug affects multiple users.

[Colin 't Hart (colinthart)]

Still a problem in 22.04 Jammy.
Very easy to reproduce. Do a minimal install of Xubuntu, install x11vnc, then run
x11vnc -quiet -auth guess

Ignore the no password warning; the error follows immediately:

/tmp/fd.eOPlUT: 1: netstat: not found
