Ubuntu mainline kernel downloads [SOLVED]
« on: April 27, 2018, 07:56:43 am »
Hi everyone,

Being one of those who likes to experiment with the newer kernels in some of my PeppermintOS installations, I have noticed at the Ubuntu mainline kernel download site that the recent kernel releases v4.16.4 and v4.16.5 have (for the amd64 builds) some packages that I have not noticed before, namely the ones whose names begin with:

Code: [Select]
linux-image-unsigned-and

Code: [Select]
linux-modules-
Can someone here tell me what these are and why they are present? And where are the ones named simply linux-image-xxx ??  :-\

Regards,

-- Slim

If I had to guess I'd say they're not signed so may not be bootable with secureboot enabled.

AFAIK those aren't default kernels in any *buntu, so they probably haven't bothered getting them signed for secureboot.

Hi Slim,
I would be careful with the 4.16.4, I got it on Void yesterday and it drops me to a repair shell. Complaining that it can not mount root fs because it lacks crc32c driver. I've loaded the missing driver and tried to re-build initramfs but, the repair shell doesn't recognize the re-build command. Also, this driver shouldn't be required for an ext4 fs [emoji848]

Don't know how the 4.16.5 works yet, the building system in Void is busy building the latest libressl and Qt5, so 4.16.5 is not available yet [emoji26]

What I can tell you is that 4.16.3 works like a charm [emoji6]
That’s what I'm currently using.
I've been using the 4.16 series since rc5 (20th of March) without any issues until yesterday...

If I have time tomorrow, I'll be compiling and building the 4.17.0rc2 [emoji38]

EDIT: If you, at any time feel curious about a specific kernel and how it behaves, just ask. I'm usually running the latest possible.

Hi Slim,
I would be careful with the 4.16.4, I got it on Void yesterday and it drops me to a repair shell [...]

Don't know how the 4.16.5 works yet [...]

4.16.4 & 4.16.5 binaries work fine on my 32-bit Peppermint Dell Dinosaur. The trick is to install 'linux-base_4.5ubuntu1_all.deb' first.

Can't install them on my 64-bit machines because I run UEFI/SecureBoot and need signed modules.

Thanks for the quick replies from everyone!!  8)

@PCNetSpec: I don't use Secure Boot or UEFI on the computers where I experiment with new kernels (and I only use the "stable" releases, none of the release candidates). The last one I installed (and which runs really well on my machines) was v4.16.3 as the later ones all had the "unsigned" images.

But now that you guys cleared that up for me I'll be installing the newest one (currently v4.16.5 as I write this). Thank you, VinDSL, for the screen shot showing what you downloaded so I can move forward with this.

@pin: Thanks for the warning. I have only one other distro that I fool around with (Arch Linux) and so far everything is stable here. Keeping my fingers crossed, knocking on wood and all those other sure-fire measures ...  :P :P

Regards,

Here is why I can't boot into those kernels, https://github.com/torvalds/linux/commit/a45403b51582a87872927a3e0fc0a389c26867f1
Linus himself is the cause of the trouble [emoji23]...ext4: always initialize the crc32c checksum driver
Bad luck Void is in the middle of libressl build and the needed patches are on the waiting list.
Guess, I'll be booting 4.16.3 for a couple of days [emoji26]
But after that I'm saying hello to 4.17.0rc2, which I built this morning [emoji6]

Heh! I'm at a Teamster PAC Meeting in Scottsdale, as I type - on Peppermint, of course.

I'm running 4.15.7 today.

Enough said?  8)

Right, but ...

I learned my lesson with the latest winders fiasco.

If it ain't broke ... you know?  ;)

Okay, back at it.

Not at all, bro. Too much coffee, sitting in a room full of my peers - that's all.

What I meant was ... it's the wrong place to be having problems with your lappy. Everyone wants to appear serious, professional, and act like they're paying attention to the political strategists' presentations. If you're dancing on the keyboard, trying to get your PC working, they think you're playing around, texting in the forums (ahem), blogging or whatevs, instead of paying attention to the proceedings. BTW, the session is over for today, so I can take the time for a proper explanation.

Didn't mean to sound like a nancy boy poofter ...  ;D

Hrm ..

Decided to throw caution to the wind and install the 4.16.5 mainline kernel on my Dell 7010 SFF box.

Installation went well ('linux-base_4.5ubuntu1_all.deb' pre-installed)

And, it booted and runs just fine.  :)

Hi VinDSL,

Got it running here too:

Code: [Select]

Linux x10 4.16.5-041605-generic #201804260630 SMP Thu Apr 26 10:32:51 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Nice.  8)
