Hello, Thank you for taking the time to report this bug and helping to make Ubuntu better.
As diagnostic procedures, I can suggest: You could try rebooting, hitting the key to get the grub menu (Shift, see https://askubuntu.com/questions/16042/how-to-get-to-the-grub-menu- at-boot-time) and choosing the previous kernel, to see if that fixes the issue you're seeing. If so, it might well be related to the kernel upgrade. Then, /var/log/apt/history.log will tell you exactly what (and when) was upgraded. That said, The problem as you reported is not related to the Canonical SSO provider or service. I'll move it to the "Linux" package, since per your description it seems to correlate with a kernel upgrade. Note that you will be required to provide more debugging information as per the kernel debugging procedures. https://wiki.ubuntu.com/Kernel/Debugging/Symptom ** Project changed: canonical-identity-provider => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1780103 Title: Network namespaces support for non-IP suddenly missing Status in linux package in Ubuntu: New Bug description: I run 16.04, and I keep daily track of all dist-upgrades. Yesterday (3 july 2018) there was an upgrade, and it must have been a kernel upgrade, because my machine had rebooted (which I make it do automatically if needed). From today, the system tests on my project have stopped working (C development). These system tests do the following: using the 'ip' command, they set up several network namespaces, in which I run several executables concurrently, that exchange network messages with each other. The namespaces that use IP have kept on working, while the ones that don't (I'm implementing an ethernet network packet structure of my own) have stopped working. I've done the same tests on my laptop, which is also a 16.04, on which I haven't done the upgrade (and I'm very hesitant to do so now, because this is my bread and butter), and there they work still.
