Public bug reported: 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).
