Linux headers for Stretch rc1

[gnipper]

Have just installed Stretch rc1 which uses kernel version 4.8.0-2. But there don't seem to be any linux headers for this kernel, only 4.9.0-1 in the repositories. Any suggestions on how to proceed when building a kernel module?

There are no Debian release candidates. The installer was rc1, not the OS. The installer probably has 4.8. You have a non-release now (testing), it does not have a specific kernel, but one that changes all the time. Since 4.9 kernel is there in the repo,I suggest you first check what kernel you have and the update your system.

Code: Select all

uname - a
apt update
apt upgrade

Many thanks for the quick response, makes sense now. Kernel 4.8 was installed by the rc1 installer but a system update/upgrade did not change the version at all. I had to specifically install linux-image-4.9.0-1-amd64, then reboot and everything was good.

You can install a linux-image metapackage*, which will automatically pull in whatever the latest kernel is--so when 4.10 gets into Stretch, that will be pulled in by an upgrade to the metapackage. You'll have to manually remove any older unwanted kernels.

*For you, that's linux-image-amd64.

And linux-headers-amd64

Yes, the metapackages sound like the answer. Much appreciate everyone's help.

OK. I thought that the installer would install the metapackages but I guess it doesn't?

^ If that is true then it sounds like a bug in RC1 to me...

@OP: can you confirm and reproduce?

I will try myself when I have time.

I recall being offered the choice between the metapackage and the specific kernel pkg, but that was the Jessie installer, and the "advanced" install path - I would expect the 'standard' install to use the metapackage by default..
