Hi, Groovy Gorilla (20.10) has just been released shipping glibc 2.32 [1] bringing many new and also numerous deprecated features. The deprecations such as the removal of Sun RPC and NIS development files are partially mitigated by adding rpcsvc-proto, libtirpc-dev and libnsl-dev to libc6-dev's dependencies to minimize the number of packages failing to build in 20.10. Eventually those dependencies will be dropped thus if you discover that a package build relies on files not shipped in libc6-dev anymore please add the new build-dependency directly.
If you would like to offer a Ubuntu-specific patch for glibc you are welcome to file merge proposals against the new glibc packaging repository [2]. Focal Fossa (20.04 LTS) has recently received a glibc update [3] improving support for the POWER10 [4] architecture and working around a limitation that prevented upgrading to and using 20.04 LTS in many ways on WSL1 [5] (WSL2 did not have this limitation). Bionic Beaver (18.04 LTS) is about to receive a glibc update [6] including a vast amount of stability and performance fixes by merging all of upstream's back-ported changes for 2.27 [7]. The update also adds a new binary package, libc6-lse on arm64 for optimized performance on systems supporting the large-system extensions (LSE) [8].
