@DanglingPointer #55 "If you want to stay with Ubuntu 20.04 LTS with latest stable mainline, you'll need to build it."
not true... if not have external kernel modules (ex. using dkms builded module for VirtualBox, Nvidia, tlp, wifi driver for card not supported by mainline, etc..) then only not install problematic linux- headers-5.13.2-051302-generic package in other case, is possible install it via "workaround"... # only unpack without install/configure dpkg --unpack linux-headers-5.13.2-051302-generic_5.13.2-051302.202107141437_amd64.deb in /usr/src/linux-headers-5.13.2-051302-generic/ replace this files: "scripts/basic/fixdep tools/objtool/fixdep tools/bpf/resolve_btfids/fixdep scripts/mod/modpost tools/objtool/objtool" from: linux-headers-5.11.16-051116-generic_5.11.16-051116.202104211235_amd64.deb (latest headers package version before switch to glibc 2.33) # configure it with ignoring libc6 depends: dpkg --configure --ignore-depends=libc6 linux-headers-5.13.2-051302-generic # fake libc6 depend version in dpkg status file sed "/Depends: linux-headers-5.13.2-051302, libc6/s/libc6 (>= 2...)/libc6 (>= 2.31)/" -i /var/lib/dpkg/status i using this workaround with my own tool for installing "Ubuntu Mainline Kernel" on all my Xubuntu 20.04 machines and without problem from 5.11.17 to latest 5.13.2 ;-) -- 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).
