Hi,
First of all, sorry for my bad english. I Tried to do my best in this text
I'm using KDE Neon, that is based in Ubuntu LTS. I Tried to run this script today and I Get this error:

"Abort, this script is only intended for Ubuntu and LinuxMint"

In theory it was supposed to work, cause the KDE Neon is based on Ubuntu 16.04. So a quick look at the code, I saw this:

OS=$(lsb_release -si 2>&-)
[[ "$OS" == "Ubuntu" ]] || [[ "$OS" == "LinuxMint" ]] || {
echo "Abort, this script is only intended for Ubuntu and LinuxMint"
exit 2
}

so I figured that adding "neon" after Linux mint with the same syntax this work. And yeah I was right, that worked without any alteration on my system, all dependencies were already installed.

So the question is, Why limit this script only to Ubuntu and Linux Mint if there are many other distros based on them?

The attach below is the patched script to work on Neon. If you need some help to test your script in other distros based on Ubuntu, please tell me. I love testing other systems 👍

Hope it helps. Thanks a lot!

My wireless dropped just before I went to check for kernel updates and the following happened:

Finding latest version available on kernel.ubuntu.com:
Finding latest installed version: v5.8.14
A newer kernel version () was found but the build was not successful

To verify:
I enabled wireless, checked for updates, and it worked as expected.
I disabled wireless, checked for updates again, and again it did that (see above).

Thanks!

Ah, that dreaded unnecessary apostrophe:

-d, --debug Show debug information, all internal command's echo their output

Imagine that you have kernel and then later you decide to install the low-latency variant of that same kernel. While this script has the ability to remove kernels installed by the script, it won't help in this case. For example, from a test machine:

$ ubuntu-mainline-kernel.sh -l
v5.8.3-050803
v5.8.3-050803

Ideally, the low-latency variant should be included in the name.

e.g. I had to reinstall the nvidia drivers. My wifi drivers (rtl8812au-dkms) and virtualbox do no longer work!

Note that the generic and snapdragon flavors are separate for arm64 and should not be installed together. (This is like installing generic with lowlatency.)

Unless I am mistaken, there is no option to install the newest kernel only if it isn't already installed.

When attempting to run with -ll switch, only linux-headers-[VERSION]-lowlatency is installed (with errors, as it depends on linux-headers-[VERSION]). Generic kernel of same version installs fine, as it installs both linux-headers-[VERSION] and linux-headers-[VERSION]-generic. Only way to install RT mainline with this script is to first install generic mainline.

Hello,

this is the output I get running the latest RC already:

Thanks and best regards,

Currently the script lets me know it's downloading the .deb files, by updating a number indicating percentage completion.

When it comes to installation, everything is silent, I've wondered a couple of times if anything is happening (my machine is relatively old, so it takes a while to install). I'm not after anything flash, a similar increasing % indicator would be great. Of course, this is not at all high priority, more a nice-to-have

Cheers

I've got ZFS root with ubuntu 20.04. The script indicates it has worked, and i can see the entries in /boot like they used to be, but the grub-update step never finds them.

From 4.16.4 onwards it stops pulling the linux-image deb package. Because the package file add an "unsigned" word with the name.

It used to pull 5 files, but after 4.16.4 it's pulling 4 files and missing the linux-image-unsinged file.

Can you please look into it and fix it.

Hello !
First thank you for your little but very useful script !
Wanted to tell you that those days I encounter a little problem :

Current kernel running: Linux 5.7.0-050700rc7-generic

I'm on kernel Linux 5.7.0-050700-generic, and I would like to update it, but when I issue the command

sudo ubuntu-mainline-kernel.sh -i

This is the response:
Finding latest version available on kernel.ubuntu.com

Abort, the amd64 build has not succeeded

I was running the script freely believing that as long as I didn't use sudo nothing would be changed, since that's the default behaviour of almost every script and application I've used.

The problem of using sudo inside the script is that if a command was run with sudo before the script most terminals will not prompt for a password again. Eg:

sudo find ./ -name something
./ubuntu-mainline-kernel.sh -i 5.3.0

No privilege elevation will be done explicitly and the script will still download and install kernel 5.3.0

Hi there,
As someone who needs to download and install the lowlatency versions of the kernel, I have been struggling recently with finding a replacement for other tool(s). Which for one or other reason(s) were broken in various ways.

Thank you for taking the time to write and be providing this script, since it works much more as expected, and with little fuss or issues. The command line flags and usage is exceptionally easy to the the end user. Kernel installed! - Thank you so much. Look forwards to re-running this tool again and again. Many times in the future. Kind regards.

Is Ubuntu 14.04 trusty supported?

I think the script should check if the user is root while trying to install a new kernel.

Instead, as of now, it just outputs as if the kernel was installed (which it didn't)

Hi,
On ubuntu Focal, i receive this error after installed libssl1.1, how can i i solve?

Either something went wrong with the kernel build or the build process has changed for the ubuntu mainline kernels. The issue seems that the linux-image files for amd64 are unsigned and are therefore not picked up by the script. Also a new file linux-modules seems to be listed.

Will need to find more info about this to see whether we need to adjust the script or this was a one-time thing.

Possible refs:

• https://askubuntu.com/questions/1027414/build-failed-mainline
• https://askubuntu.com/questions/1028629/kernel-ubuntu-com-kernel-ppa-mainline-v4-16

The help output says:

You don't have to prefix with v. E.g. -i 4.9 is the same as -i v4.9.

However the output of ubuntu-mainline-kernel.sh -r 4.9 ends with:

v4.14.98        v4.14.99        v5.4.9

Omitting the v enables substring matches which can lead to install making the wrong choice.

It seems better to treat 4.9 as v4.9., internally.

You close the issue #7 too quickly ...I am running 18.04 ,,,,then the solution to #6 will work??

if not what would be the clue???

The kernels installed by this script are completely unsupported, and not intended for end-users. Their intended use case is as a convenience in debugging issues with Ubuntu provided kernels.

They get no bug fixes and are not covered by any security guarantees. As such, a user who installs and runs with a kernel setup in this manner is opting out of security updates provided by the official Ubuntu kernels in the default archive.

While I appreciate the rationale some have for installing new kernels (performance, bug fix, hardware support etc) it should be done with informed consent. The user should be told that they're not going to get support for these kernels, and are not covered by security updates.

Perhaps there should be both a warning at the top of the README.md for this repo, and in addition when the user runs the script, at least for the first time, if not every time, that they're going "off piste" when it comes to security updates and support.

Now debs appear to be in arch specific subfolders.

Support for installing / uninstalling RC versions should be improved as there are currently some issues with it.

See #33 and #36

I can't uninstall two kernels instaled with the script.

Are you really sure? Do you still have another kernel installed? (y/N)

It's end and do nothing.

The debug shows
/usr/local/bin/ubuntu-mainline-kernel.sh: linha 783: DEBIAN_FRONTEND=noninteractive: comando não encontrado

download kernel to relative path assigned by -p will fail.

it complains that the downloaded file not found.

Here is what I am seeing this morning:

Finding latest version available on kernel.ubuntu.com Latest version is: v5.9.5 Abort, the amd64 build has not succeeded

I still get the desktop alert that a newer kernel is available. Maybe this could be handled better?

When I first discovered this script, only 2 days ago, I mistakenly forgot to run it via sudo. The script acted like it installed the newest kernel but it was only after I rebooted that I realized what I had done. Some sort of check before exiting the script would be very helpful.

Thanks!

Goodmorning,
the cleaning operation (sudo kernel-remover -f) doesn't remove the package:
linux-headers-OLD-VERSION*
when there is already installed the new... is a bug?

Thanks

Running ubuntu-mainline-kernel.sh -u <version> with a previously installed version doesn't uninstall the kernel as expected.

Running the script with --debug leads shows the following error:
/usr/local/bin/ubuntu-mainline-kernel.sh: line 783: DEBIAN_FRONTEND=noninteractive: command not found

I'm running Ubuntu 20.04, with 5.4.20.

the files are now stored in separate sub-directories, as of 5.7.2. one sub-directory for each architecture

e.g.
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.7.2/amd64/

the latest install is failing with an "Expected to need to download 6 files but found 2, continue? (y/N)" error

Running on an amd64 system today shows this:

./ubuntu-mainline-kernel.sh -c
Finding latest version available on kernel.ubuntu.com: v4.20.2
Finding latest installed version: v4.20.0-042000
A newer kernel version (v4.20.2) is available

However as per https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20.2/ the amd64 4.20.2 kernel failed to build properly

Build for amd64 failed (see BUILD.LOG.amd64):
  linux-headers-4.20.2-042002_4.20.2-042002.201901130931_all.deb
  *_amd64.deb

Ideally the script should check to make sure there isn't a "Build for arch failed" line before reporting that kernel as available for the arch the script is being run on.

After I do "ubuntu-mainline-kernel.sh -u" and select the kernel to uninstal, the script asks:

"Do you still have another kernel installed? (y/N)"

I'm sure we could check for another kernel installed, either from ubuntu-mainline-kernel.sh or from other (apt) sources. If there isn't a positive from either of those sources, then ask if there is another kernel installed.

Yes, it's minor, it's a small usability thing, not at all high priority.

While downloading big file people should be aware that something is happening in front of their eyes instead of in the background. A progress bar on the terminal would nice ...I mean fetching can be done in the foreground too..more visible stuff

like in dd or pv

--status=progress

After kernel 5.7.2 there is new folder structure. So this script always shows build failed.

Not in the background ..that is very very important ...the output of removal/purge should be visible...so end user can see what is happening!

I wanted to install a new kernel because I have problems with my wifi card which is supposed to be solved by updating the kernel. Thus I use the ubuntu-mainline-kernel.sh script, but after installation I get ‘/vmlinuz-5.7.7’ not found and I cannot boot the system. Any ideas?

Is it possible to change the downloader from wget to aria2c since it does support checksums and parallel downloads natively?

This issue persists while installig the last kernels. Installing itself is fine:

It would be cool to have a --self-update option to easily update the script

with sudo ubuntu-mainline-kernel.sh -i I installed the latest linux kernel (5.5.7). It did not work for me, so I booted using another version (5.5.0). Then removed version 5.5.7 with sudo ubuntu-mainline-kernel.sh -u. However, now when I boot, I still get linux kernel 5.5.7, which should be removed. Any ideas how this is possible?

Hi,

I am running Pop!_OS 19.10 and ran ubuntu-mainline-kernel.sh to see if the latest kernel handles the OLED screen brightness issue. (Unfortunately, it does not :( )

I am curious about how to switch back to the kernel before running the script? Now I can only see one available kernel, which in the latest one, after ubuntu-mainline-kernel.sh -l

Thanks.
