I think we're getting way off topic here. The fundamental issue in this bug report is that the policy being employed when building the mainline kernels does not follow the policy documented. Either the mainline builders need to start following the policy (and building on LTS) or change the policy (and continue building on Ubuntu "next").
If you use my PPA and have questions about it, then please open an issue on the github project here: https://github.com/TuxInvader/focal- mainline-builder DanglingPointer (cool handle) is correct in a lot of what he said, there is no inherent trust conveyed through the PPA system. Any one can setup a PPA and upload software packages to launchpad. Downloading software from a PPA is little different to downloading a snap or binary package from a website. You need to decided whether you want to trust the origin. I would like to point out the following though: 1. PPAs aren't compiled in the uploaders basement, a source package is built and uploaded to the PPA and then the compilation takes place on launchpad. I'm not suggesting this is more secure obviously. I could still have messed with the source package ;-) 2. Kernel PPAs are not more of a threat to your system than any other PPA. Your kernel runs your hardware and has full access to the system, but does a malicious kernel module have more access to your data (read the stuff you care about) than your user account? Beware of all PPAs, not just ones which package kernels. In the interest of transparency, I have reverted my docker container to use the official dwarves package. If you want to use my container to build your kernel you can now see everything it does, it is after all a shell script. If you chose to continue using my PPA, then I would also point out that those binaries are built using my dwarves package, because that's just how launchpad works. Cheers :-) PS. If you're not using 5.12.x, then you may have noticed that mainline hasn't built any packages for a while, 5.11.x and 5.10.x started failing around the time they switched to impish, and coincided with the build machine running out of disk space. I opened a report here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1928535 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1926938 Title: Recent mainline packages are built with Hirsuite 21.04, not Focal 20.04 LTS Status in linux package in Ubuntu: Confirmed Bug description: Hi all, The Mainline wiki states that the mainline kernels are built with the previous LTS toolchain, but the recent 5.12.x and 5.11.x releases are being built with Hirsuite 21.04, and before that Groovy? If this is intentional, then the wiki should be updated to reflect the change in policy. From https://wiki.ubuntu.com/Kernel/MainlineBuilds Mainline kernel build toolchain These kernels are built with the toolchain (gcc, g++, etc.) from the previous Ubuntu LTS release. (e.g. Ubuntu 14.04 "Trusty Tahr" / 16.04 "Xenial Xerus" / 18.04 "Bionic Beaver", etc.) Therefore, out-of-tree kernel modules you already have built and installed for use with your release kernels are not likely to work with the mainline builds. The 5.12 kernel was built with GCC 10.3.0, and 5.11.16 with 10.2.0. On my Focal LTS system I have GCC 9.3.0. The Mainline kernel build toolchain These kernels are built with the toolchain (gcc, g++, etc.) from the previous Ubuntu LTS release. (e.g. Ubuntu 14.04 "Trusty Tahr" / 16.04 "Xenial Xerus" / 18.04 "Bionic Beaver", etc.) Therefore, out-of-tree kernel modules you already have built and installed for use with your release kernels are not likely to work with the mainline builds. The *linux-headers-generic* packages have unmet dependencies on 20.04 LTS. I could install Groovy built kernels fine, but the Hirsuite ones built with GCC 10.3.0 appear to require libc6 >= 2.33. So the new kernels can't be installed on Focal (libc 2.31).
