  1. UPDATE Ubuntu 20.04 will ship with 5. 4

    https://www.omgubuntu.co.uk/2020/02/ubuntu-20-04-kernel-5-4-lts

    The plan is to release Ubuntu 20.04 with the 5.5 kernel. The 5.4 kernel has already been confirmed but the release of the 5.5 kernel is inside the possible window for the 20.04 release. Kernel 5.6 is likely to arrive too late.

    Some sources: Phoronix

    While WireGuard was merged into Linux 5.6, the Ubuntu 20.04 LTS release is currently tracking Linux 5.4 and for the April release is likely to be shipping with Linux 5.5 as the 5.6 release will be cutting it too close. But Ubuntu 20.04's kernel has now back-ported WireGuard.

    OMG Ubuntu:

    Kernel Freeze: April 9, 2020

    Other planned changes to Ubuntu 20.04 LTS include:

    • GNOME 3.36
    • Linux Kernel 5.5 (or newer)
    • Improved ZFS install support

    As I like to live dangerously. 20.04 currently installs:

    $ uname -a
Linux schijfwereld 5.4.0-12-generic #15-Ubuntu SMP Tue Jan 21 15:12:29 
UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

  2. Ubuntu 20.04 has been using the 5.4 awhile now, Ubuntu 18.04 LTS with HWE enabled will eventually use the 20.04 kernel, but not until 18.04.5 is reached (for ISOs, installed systems get it a little earlier).

    • Ubuntu 18.04.2 was 18.10 stack,
    • Ubuntu 18.04.3 was 19.04 stack,
    • Ubuntu 18.04.4 uses 19.10 stack,
    • Ubuntu 18.04.5 uses 20.04's stack (the last stack upgrade for 18.04)

    HWE for prior LTS is behind to ensure stability; likewise the offer to upgrade to 20.04 isn't offered for 18.04 users until 20.04.1's release ensuring stability for users.

    We are only approaching the official release of 18.04.4 (ie. 19.10 stack for 18.04), so 18.04.5 is still awhile into the future.

    Refer @Rinzwind's answer for details on 20.04
