Linus Torvalds announced the 5.4 Kernel on lkml.org:
“Not a lot happened this last week, which is just how I like it. And as expected, most of the pull requests I got were for the 5.5 merge window, which I’ll obviously start working through tomorrow.”
Linux 5.4 Kernel brings a lot of new hardware support，including AMD Arcturus GPU, Navi 12 and Navi 14 GPUs, AMD Dali and Renoir APU support，Intel Tiger Lake “Gen 12” graphics，Qualcomm Snapdragon 855 SoC, Intel Ice Lake Thunderbolt support. The new release also features Logitech Linux LOCKDOWN LSM, Lightspeed receiver support, Microsoft exFAT support, and a plethora of other new features and improvements.

Depends on your OS type, download and install the packages in turns:
generic for common system, and
lowlatency for a low latency system (e.g. for recording audio),
amd64 for 64bit system,
i386 for 32bit system, or armhf, arm64, etc for other OS types.
Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):
For 64-bit OS:
cd /tmp/ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-headers-5.4.0-050400_5.4.0-050400.201911242031_all.deb wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-headers-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-image-unsigned-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4/linux-modules-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb sudo dpkg -i *.deb
