I've been considering lowering the timeout in apt from 120s to something like 10-30s for a year or two, but there's been some concern about high- latency connections. I personally do not think that 120s is a sensible timeout for one round trip.
There are also several options to prevent this issue on the network side: - do not provide DNS servers / resolve internet names - do not drop packets, but reject them - point a SRV record in your DNS server to a working HTTP host (either serving the archive, or 404, as long as it connects, it should be fine) We also had the same issue on some IPv6+IPv4 systems where the IPv6 is not reachable, but that's fixed in cosmic with happy eyeballs falling back to the next host within milliseconds (trying more and more hosts in parallel until one works). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766542 Title: Installation blocks when the machine is behind a proxy server To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1766542/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
