Whilst reproducing and simulating bug #1150517 "awk: line 2: function
gensub never defined" and therefore mDNS using resolvectl, I noticed
that in my local network where it listens on port 8000:
$ resolvectl service "Squid deb proxy on noc systemd._apt-proxy._tcp.local"
Squid deb proxy on noc systemd._apt-proxy._tcp.local: noc.local:8000 [priority=0, weight=0]
10.254.33.2 -- link: cameras.33
(Squid deb proxy on noc systemd/_apt-proxy._tcp/local)
detect_squid_deb_proxy only tests the hard-coded port:
[2026-10-10T18:25:19+00:00] auto-apt-proxy: DEBUG: looking for squid-deb-proxy at http://10.254.33.2:3563
I'm working on a fix for this; an MR will be forthcoming.
