I've got squid-deb-proxy, avahi-tools, and squid-deb-proxy-client installed on a gateway VM running 12.04 Server, and squid-deb-proxy-client installed on two client VMs running Lubuntu and Xubuntu 12.04.
The service appears to be up and running according to htop, and I can see considerable activity when the clients update/upgrade, and I see activity in the log files... but I'm not seeing any cache being stored in /var/spool/squid3 - or anywhere else.
What should I be looking for to tell if its really working?
sudo start squid-deb-proxy-avahi
line in that other thread... it does not appear to work in 12.04 LTS. – memilanuk May 14 '12 at 20:47
