I have seen similar posts and read the documentation. But as to my original questions -- can I build a sid based version on a jessie box? Also, can you fix the linux-source-4.1 package and explain to me how to install the linux-headers package which will not install?

Thanks.

Hi. I want to make a grml cd with some kernel changes and adding some packages. Now, I am using a system based on Jessie, but I want to build based on sid. I tried to install the linux-header package, but it would not install saying it needed kbuild4.1 which cannot be installed. Also, I tried to install the linux-source-4.1 package, but ehe .xz file is broken (unrecognized file format) when using tar Jxvf .

How to solve these problems?

Thanks in advance for any suggestions.

Basically yes, our daily ISOs (http://daily.grml.org/) are also generated on a Debian/jessie system. Though sid AKA unstable might be broken from time to time (that's the nature of it and why it's called unstable) and you should be familiar with unstable to work with it. I'd recommend usage of stable or testing if possible.

I've no idea what's your problem with linux-source-4.1 and the linux-headers package. :) Please cite the exact error message as a starting point.

When I install the linux-source-4.1 package using your repository, I get a tar.xz file and when I try to unpack it, I get the message file format unrecognized. This would lead to the conclusion that the package is broken.

Since you don't post your exact command line I'm assuming you're missing xz-utils being installed to have proper xz support?

Its the xz partwhich did not recognize the file system. I did tar Jxvf on the file and tried just with xz -d with same result. Can you check it yourself?

Thanks.

Works fine for me:

% wget http://deb.grml.org/pool/main/l/linux/linux_4.1.7.orig.tar.xz % tar atf linux_4.1.7.orig.tar.xz | tail -5 linux-4.1.7/virt/kvm/eventfd.c linux-4.1.7/virt/kvm/irqchip.c linux-4.1.7/virt/kvm/kvm_main.c linux-4.1.7/virt/kvm/vfio.c linux-4.1.7/virt/kvm/vfio.h tar atf linux_4.1.7.orig.tar.xz 6.36s user 0.41s system 108% cpu 6.248 total tail -5 0.03s user 0.23s system 4% cpu 6.248 total

But that was not the one I tried to install -- I tried to install by doing apt-get install linux-source-4.1 tar Jxvf linux-source-4.1.tar.xz and this gave me a broken file.

# apt-get install linux-source-4.1 # cd /usr/src # file linux-source-4.1.tar.xz linux-source-4.1.tar.xz: POSIX tar archive (GNU) # tar atf linux-source-4.1.tar.xz | tail -5 linux-source-4.1/virt/kvm/eventfd.c linux-source-4.1/virt/kvm/irqchip.c linux-source-4.1/virt/kvm/kvm_main.c linux-source-4.1/virt/kvm/vfio.c linux-source-4.1/virt/kvm/vfio.h

So don't add the "J" option to the tar command line and it will work just fine.

OK, very unusual, but I will certainly try that -- thanks.

OK, thanks -- that indeed did work, although I don't quite understand why.

Because as stated above in:

# file linux-source-4.1.tar.xz linux-source-4.1.tar.xz: POSIX tar archive (GNU)

it's a plain tar file and not further compressed, so the file extension is misleading.

(I don't know why that's actually the case, I'll try to keep an eye on it for our next kernel build.)
