I notice the dbg package for the kernel was moved, but it doesn't appear to be installable.
I've added the necessary entry to /etc/apt/sources.list: deb http://debug.mirrors.debian.org/debian-debug/ stretch-debug main non-free contrib and then I try to get the package: # apt-get install -t stretch-debug linux-image-amd64-dbgsym Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: linux-image-amd64-dbgsym : Depends: linux-image-4.8.0-2-amd64-dbgsym but it is not installable E: Unable to correct problems, you have held broken packages. It looks like the kernel was built over a week ago: # uname -aLinux srv1 4.8.0-2-amd64 #1 SMP Debian 4.8.15-2 (2017-01-04) x86_64 GNU/Linux so would the dbgsym package still be in Incoming?
