Ask us anything about Ubuntu Kernels!

It seems the apparmor patches for full snap confinement has finally landed
(snapcraft.io forum post)

great, seems it landed for 6.17 – https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8b45c6c90af6702b2ad716e148b8bcd5231a8070

I guess canonical will drop the ubuntu sauce then? As far as the forum knows, it needs apparmor 4.1 to work (which is in the 25.04 snapd deb package) but is not yet in the snapd snap.
So my understanding for older ubuntu one would need a backport/snapd snap in order for full confinement with the 6.17 kernel. Is that right?

A post was split to a new topic: Free disk space by removing kernels

After kernel v5.19 we had 6.0, next will be v6.20 or v7.0?

Good question. As far as I know, bumping the kernel version number and resetting the patch-level back to 0 is at the whim of Linus Torvalds. However, it does seem somewhat consistent at around after patch-level 19 or 20.

Just a question : my laptop has :

Welcome to Ubuntu 24.04.4 LTS (GNU/Linux 6.17.0-14-generic x86_64)

kernel 6.17.0-14 on Ubuntu 24.04.4 LTS

On multipass (for testing/playing etc.) I have :

Welcome to Ubuntu 24.04.4 LTS (GNU/Linux 6.8.0-100-generic x86_64)

Kernel 6.8.0-100 on Ubuntu 24.04.4 LTS.

What is the difference ?:thinking: Just wondering :slightly_smiling_face:

Linux kernel archives https://www.kernel.org/ reports kernel 6.19.2 while Index of /mainline stops at 6.19-rc8?

From what i can see the new 6.19.0 kernel has been build successfully so why it is not added i don’t know. Think i read somewhere that some systems didnt boot properly with the new kernel. It was fixed in the 6.19.2 i think but there is no test builds for that in mainline. From what i have seen new kernels is usually added about a day or so after official release but not this time. Hope it is tested and added soon :slight_smile: It feel that the latest kernels has been a great improvement and Linux gaming is better than ever and properly grown up and the next kernels will improve even more! Am i alone in feeling that there has been a leap lately?

The Ubuntu Resolute kernel is 7.0.0-10-generic which corresponds to Index of /mainline ? Thank you

The two kernel build processes are distinct and totally unrelated. One is automated, the other is human driven. They could be based on the same upstream version. Or not.

New 7.0-rc7 mainline kernel requires a zfs module ? How do get this package as it’s missing at https://kernel.ubuntu.com/mainline/v7.0-rc7/

Thanks for raising this issue. That new dependency is an issue for mainline builds. We don’t intend to package zfs for mainline but need to tweak the mainline packaging instead.

Thanks for the quick reply. Do you have a rough estimation when zfs dependency for mainline builds can be removed ?

For my workflow I used both Fedora automated kernel builds and Ubuntu mainline builds. Fedora’s 7.0-rc7 kernel is running fine. In the worst case if both are not available I can semi-automate my own build.

v7.0-rc7 has been rebuilt. Can you check?

hello – I can confirm that this works now. Thank you for taking the time to rebuild.

Hi,

v7.0-rc7 is working fine. Thanks! It fixes a kernel crash I’ve been having since v7.0-rc5. I also added back Ubuntu dev testing for my workflow. Fedora tends to have kernel builds a few days after Ubuntu mainline so nice to have Ubuntu mainline builds.
