How can I add the mainline kernel ppa to the synaptic software sources?

I have the url: http://kernel.ubuntu.com/~kernel-ppa/mainline/

but I am missing the ppa: line.

Note: test/debug kernel versions higher than your default kernel, e.g. 3.3, 3.4, 3.5, etc. are only provided via deb files, not via this PPA.

You probably want to add this PPA-- the only active one the kernel team maintains -- containing the latest pre-proposed kernel for each release:

ppa:kernel-ppa/pre-proposed

  • Thanks, I actually thought they were provided by the ppa above. Yes, I am looking for latest 3.5 kernel. – Paulo Matos Jul 08 '12 at 09:12

    @PauloJ.Matos : You can find the necessary deb files for the latest 3.5 here. – ish Jul 08 '12 at 09:15
  • @PauloJ.Matos Or you can install 3.5 via PPA http://ubuntuguide.net/install-kernel-3-5-rc-ubuntu-12-04-precise-using-ppa I have to admit that I don't know which is the proper source - this PPA or the debs from izx's comment. I used the PPA, installed only update entries (in update manager) that mentioned kernel, restarted and disabled the PPA via Y PPA Manager to avoid installing anything else from the PPA (xorg edgers). – Bucic Jul 23 '12 at 18:13

    @Bucic: the debs are from Ubuntu's kernel team, and your PPA is from a third party (xorg-edgers). I'd trust the former over the latter :) – ish Jul 24 '12 at 05:22

    @izx It's not like it's some lousy group known to no one, you know ;) But I agree. Upgrading to mainline kernels is not recommended unless you experience problems with you current kernel, but if you're upgrading to mainlin it better be from ubuntu team :) – Bucic Jul 24 '12 at 07:35

    This PPA appears to have been abandoned. "Number of packages: 0 source packages (0 bytes) 0 binary packages (0 bytes)". Just the http://kernel.ubuntu.com/~kernel-ppa/mainline/ page is left, but I don't want to install unauthenticated packages. It's not HTTPS and there is no GPG signature for the builds. No go for me. – gertvdijk Apr 30 '15 at 00:54
  • @gertvdijk This may have changed since you wrote that but the checksum files for the builds on kernel.ubuntu.com are gpg signed. Granted this isn't perfect but if you can hack a SHA256 and the SHA1 for a file, you probably have enough compute power to just MITM a SSL connection. It's secure if you're diligent enough to check it. – Oli Aug 09 '16 at 14:01
  • @Oli Ah, that's definitely new. The CHECKSUMS / CHECKSUMS.gpg weren't present before. Great :) – gertvdijk Aug 09 '16 at 14:16
  • I suggest using the ppa:canonical-kernel-team/unstable PPA - it tracks mainline and may include Ubuntu specific optimizations and back-ports, and it is a PPA that will update your installation automatically. Note the "unstable" tag though - though it is a given that "mainline" is already considered unstable for Ubuntu. – Guss Mar 30 '20 at 11:15

To my knowledge there is no way to add that to the /etc/apt/sources.list file There is a script that can get the job done https://github.com/GM-Script-Writer-62850/Ubuntu-Mainline-Kernel-Updater

Terminal Commands: (edit, more up to date info now in the readme at the above link)

cd /tmp
git clone git://github.com/GM-Script-Writer-62850/Ubuntu-Mainline-Kernel-Updater
bash Ubuntu-Mainline-Kernel-Updater/install

It will check for updates at login+60 seconds, you can check for updates at any time by running KernelUpdateChecker use -h or --help with that for help output

ukuu is no longer free and open, but mainline is maintained and is free & open. https://github.com/bkw777/mainline

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline

You can use Ukuu (which stands for ‘Ubuntu Kernel Update Utility’) This straightforward desktop app help you install a new kernel in Ubuntu, Linux Mint, and other Ubuntu-based distributions, using the “mainline” kernels published by Canonical.

Installation:

sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update && sudo apt-get install ukuu

Then run "ukuu" from your appplication starter and it will show you all stable kernels to choose from. If you want unstable rc-kernels, you can disable the "hide unstable and RC Releases" flag in settings

/*tested code already , 
whipped this right up hope it works for you, it downloads the latest kernel from the daily mainline , 
and checks if its on your sys if not installs it 
tested and working :) simply compile as anything .c with your gcc
download at : [here](http://ubuntuone.com/0mLWYLhGPJlHGFXONz6EcO)

  • it checks the current daily build off the ubuntu kernel mainline and updates yours if its not update already cleaned up version , no need for user input , detects the arch of your current kernel (32 bit 64 bit) here http://ubuntuone.com/0mLWYLhGPJlHGFXONz6EcO – user183601 Aug 13 '13 at 06:46
  • ok posted a link to the one on my ubuntu one and changede the code here and added

  • thanks as u can tell im new to this site , gave an answer and code and adding that now – user183601 Aug 13 '13 at 15:26
  • update : in the link changed it to use uname -v instead of uname -r to check against the other one on this newest update didnt upgrade the others did so now it will :)) fixed it on that part :) and also if your running ubuntu 13.04 32 bit of it think it may b compatible get the binary from http://ubuntuone.com/3cwJte3KtfNNnGcrMcnl6B – user183601 Aug 26 '13 at 21:22

    Why on earth is this a C program invoking system(3) rather than a shell-script? O_o – liyang Apr 14 '15 at 13:28
  • @liyang In order to minimize readability? I was actually wondering the same thing, I was baffled to find this answer . – xolox Aug 05 '19 at 14:27
