The Linux Kernel 5.15 LTS has been released, and below we will show you how to install it on Ubuntu or Linux Mint distributions in a few easy steps.
The Linux Kernel 5.15 was released on October 31, 2021 and brings some interesting new features, such as a new NTFS file system application that does not require you to use third-party software such as NTFS-3G to fully manage NTFS disks.
It also offers some new features for them users of Btrfs and XFS file systems, support for Nintendo Wii consoles, support for multicast per VLAN, in-kernel SMB server, new r8188eu Realtek wireless LAN driver to replace the old rtl8188eu driver, and more.
Best of all, the Linux Kernel 5.15 is in the LTS kernel series (Long Term Support), and will be supported for at least two years.
And now the eternal question… why upgrade the Linux kernel? If the possibilities mentioned above do not excite you, do not do it.
But if you need support for existing or new hardware supported by Linux Kernel 5.15 or if you are having hardware issues with the current kernel version, why not give it a try.
Warning! You should be aware that Linux Kernel 5.15 has just been released and may not be supported by all software programs or drivers, such as the proprietary NVIDIA graphics driver. So if you are using NVIDIA GPU for games or anything else, you'll have to wait until NVIDIA starts supporting Linux Kernel 5.15.
Below we will use the Ubuntu kernel PPA file provided by Ubuntu developers. These kernel packages are not signed, which means that they cannot be installed on UEFI / Secure Boot systems. Therefore, you must first disable Secure Boot to install the 5.15 kernel.
