In addition to the upstream deprecations, please note that since Ubuntu 20.04 (Focal Fossa), the security level 2 (which is the default) disables the (D)TLS protocols below 1.2 (included). In particular, certificates using SHA1 or MD5 as hash algorithms are now invalid under the default security level. We’ve upgraded the OpenSSL library to the new 3.0 version, which disables a lot of legacy algorithms by default, as detailed in their migration guide. The OOMD status can be checked using oomctl. We’ve enabled the userspace OOMD service and are shipping the systemd-oomd package by default on the “Ubuntu Desktop” flavour, to avoid overloaded systems and the need of the kernel’s OOM killer to kick in.

Please refer to the upstream changelog for more information about the individual features. The init system was updated to systemd v249, using a solid. In addition to OpenJDK 11, OpenJDK 18 is now provided (but not used for package builds). Python now ships at version 3.10.4, Perl at version 5.34.0. GCC was updated to the 11.2.0 release, binutils to 2.38, and glibc to 2.35. Mount.nfs: an incorrect mount option was specified In practice, if you try to use udp, you will get this error: $ sudo mount f1:/storage /mnt -o udp Since Ubuntu 20.10 (“Groovy Gorilla”), the kernel option CONFIG_NFS_DISABLE_UDP_SUPPORT=y is set and this disables using UDP as the transport for NFS mounts, regardless of NFS version.

Ubuntu Cloud and Devices use optimized kernels in collaboration with partners (v5.15+ with additional backports and features)Īdditional optimized and certified kernel flavours will become available in Ubuntu 22.04 LTS in due course.

Ubuntu Server defaults to a non-rolling LTS kernel v5.15 ( linux-generic).

The rolling HWE kernel is based on the v5.15 kernel for 22.04.0 and 22.04.1 point releases

Ubuntu Desktop uses a rolling HWE kernel ( linux-hwe-22.04) on all other generations of hardware.

Ubuntu Desktop will automatically opt-into v5.17 kernel on the latest generations of certified devices ( linux-oem-22.04).

Ubuntu 22.04 LTS ships multiple optimized kernels on per-product basis:
