Running apport-collect 1672455 doesn't make any sense, since the ppa- webserver is of concern here.
It is easy to confirm this bug: Just point a browser to https://kernel.ubuntu.com/~kernel-ppa ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1672455 Title: Mainline Kernel repo does not use https Status in linux package in Ubuntu: Confirmed Bug description: Mainline kernels are provided at http://kernel.ubuntu.com/~kernel-ppa This is very convenient, especially if one has the latest hardware for which older kernels often do not have hardware support. However https://kernel.ubuntu.com/~kernel-ppa does not work. I do not have a great feeling installing something as crucial as a kernel without trusting the source. Of course one could in theory try to reproduce the build by compiling from source, but in practice this is hardly a viable solutions.
