Errors in script /usr/lib/avahi/avahi-daemon-check-dns.sh

[rklemme]

In line 42 and 46 Command Substitution is used wrongly because the shell expects to execute what it returns. See attached patch.

For focal we should actually remove this script, since nss-mdns automatically performs this behaviour and doesn't rely on the "hack" of stopping avahi-daemon to prevent resolution of .local domains via DNS.

If this error is serious we could consider backport to stable releases.

(for clarity nss-mdns 0.14 does this behavior itself automatically, in 0.10 in bionic does not)

[rklemme (shortcutter)]

I think the script will still work most of the time so severity is not too high.

This bug was fixed in the package avahi - 0.7-4ubuntu7
