Here is how I setup the environment: 1. prepare a broadband gateway. This time I use LEDE with VirtualBox. I can upload the VM image if necessary. 2. add a firewall rule on the gateway: all http/https traffic from LAN port will be redirected to a IP which is not used by any machine. 3. install Ubuntu and check the behavior.
I can reproduce the issue with this environment. Even though, I'm not sure if this is exactly the same with the customer's environment. @Steve, Yes, We are using oem-config mode. With the normal mode, because it uses less archives and apt operations, the blocking time is shorter. Please see my following comments, I'll provide my results of the official 16.04 and 18.04 image. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1766542 Title: Installation blocks when the machine is behind a proxy server Status in OEM Priority Project: Confirmed Status in apt package in Ubuntu: New Status in ubiquity package in Ubuntu: Incomplete Status in apt source package in Bionic: New Status in ubiquity source package in Bionic: New Bug description: When the machine is behind a proxy server, the installation will block for a while (several minutes) to retrieve the package lists. The timeouts are too long and makes user feels the machine may have some problems. The symptom is similar with bug #14599, but it seems the apt-setup module was rewritten. Another method to trigger this issue is to make the machine cannot access to the Internet, for instance: a wrong gateway.
