Important Notes

  Warning: Manual kernel installs can become outdated

This guide installs Linux Kernel 5.10.253 manually. It is unlikely to receive automatic updates through Ubuntu's normal kernel packages, so you will need to check for newer versions yourself.

Manual kernel installs can also cause boot or hardware issues on some systems. Your current kernel is usually kept so you can switch back if needed, but use care, especially on UEFI systems.

Finally, it should be noted that this script will NOT automatically determine your system architecture, utilising only the amd64 packages for a 64bit system. ARM-type processors are not supported.
