Public bug reported: On Ubuntu Xenial, apt-get fails silently when security update server cannot be reached. This state could be detected by scanning the apt-get output afterwards. But manually adding workarounds to each apt-get invocation in production automation is prone to error, thus leaving machines without security updates.
Expected behaviour (e.g.): * 0 - all OK * 1 - temporary failure (e.g. network) * 2 - permanent failure Test: * Change your update server IP in /etc/hosts to something unreachable * Run apt-get update (might take a while) * Check exit status $ lsb_release -r -d Description: Ubuntu 16.04.3 LTS Release: 16.04 rfiedler@n3ahit1403:~$ ii apt 1.2.24 amd64 commandline package manager ** Affects: apt (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742695 Title: apt-get update silently fails fetching security updates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1742695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
