The only way to install and updatde my fresh desktop Ubuntu 18 LTS (installed by pendrive without internet) is using a proxy with a PAC file:
myip = myIpAddress(); function FindProxyForURL(url, host) { if (isPlainHostName(host)) return "DIRECT"; // Bypass Local Network if (isInNet(dnsResolve(host), "10.0.0.0", "255.0.0.0") || isInNet(dnsResolve(host), "etc", "etc") || ... || isInNet(dnsResolve(host), "etc", "etc")) return "DIRECT"; // Bypass Local IP if ( isInNet(dnsResolve(host), "etc", "etc") || isInNet(dnsResolve(host), "etc", "etc") || isInNet(dnsResolve(host), "etc", "etc")) return "DIRECT"; // Bypass URL if ((host == "domain1") || (host == "domain2") || (host == "etc") || (host == "etc")) return "DIRECT"; // Bypass Domain if (shExpMatch(url, "*.domain") || shExpMatch(url, "*.etc") || shExpMatch(url, "*.etc")) return "DIRECT"; //Encaminha todo o trafego que restante para o PROXY CORPORATIVO return "PROXY _IP_:8080; DIRECT"; }
