#173425 — New amd64 kernel in Debian x86 testing?

AFAICT, the latest amd64 kernel in Debian x86 testing is still 3.16
(i.e. the one from Debian stable).
Any idea why there's no newer one?

Do you update your software by ``apt-get update & apt-get upgrade & 
apt-get dist-upgrade''?

Since linux 4.0, the -amd64 kernel flavor is no longer built on i386:

|   * [i386,s390] Remove 64-bit kernel flavours, which are also available

To install the -amd64 kernel via multiarch, run these commands:

# dpkg --add-architecture amd64
# apt-get update
# apt-get install linux-image-amd64:amd64

Cheers,
       Sven

Hmm... that's what I thought.

Thanks.  It's kind of silly to have to download the complete list of amd64
packages, but I can live with it.

And I guess I can --remove-architecture right after that so I don't keep
downloading/updating the list of amd64 packages all the time.

It certainly slows down apt operations somewhat, also all packages show up
twice in aptitude's TUI which is a bit annoying.

No, dpkg refuses to remove an architecture as long as there are packages
of that architecture installed.  What you _can_ do, however, is to limit
the architecture list to i386 in sources.list(5), e.g.

deb [arch=i386] http://ftp.debian.org/debian/ testing main

Whether the bandwith save is worth the cost of not getting timely kernel
upgrades is debatable, of course.

Cheers,
       Sven

There are plenty.  Kernels don't get updated in the same way as other
packages.  If you want to track the latest version of the kernel,
install (in your case) linux-image-amd64.  Even then, old kernels aren't
removed on upgrade for safety reasons - in a worst case scenario, it
could leave your system unable to boot.
