[Bug 1635391] [NEW] [Regression] Avahi-daemon nss-mdns hostname resolution is deactivated since 16.10 resulting in "Unable to locate printer"

[Mathias Dietrich]

Public bug reported:

Since 16.10 Avahi-daemon nss-mdns hostname resolution for network printer is deactivated.
This causes that print jobs against these printers fail with the error "Unable to locate printer".

As a reminder, before 16.10, it hostname resolution worked perfectly.

As a workaround change the existing config entry in "/etc/nsswitch.conf" from:
hosts:          files resolve [!UNAVAIL=return] mdns4_minimal [NOTFOUND=return] dns

to:
hosts:          files mdns_minimal [NOTFOUND=return] dns myhostname
