OK, so archive.ubuntu.com has 4 AAAA and 4 A entries, meaning that 16.04 waits 16 minutes (8 * 2 minutes) 18.04 waits 2 minutes, 2 seconds (2 minutes + 8 * 250 milliseconds)
Now we can shorten that further to one of the following: * 12 seconds (10 + 8 * 250 ms) * 22 seconds (20 + 8 * 250 ms) * 32 seconds (30 + 8 * 250 ms) 30 seconds seems like a good conservative choice with reasonable behavior. -- 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.
