If you regularly use tools like the tree command to inspect directory structures, rely on multitail to monitor logs in real time, tweak firewall behavior with iptables reject vs drop rules, test sockets with netcat, navigate with the ls command, or edit configs in vim, then running a newer Linux kernel is not just a curiosity — it’s part of staying sharp and compatible with modern hardware and subsystems.

The good news: Linux Kernel 7.0 RC2 is now available for testing on Ubuntu and its derivatives, and you can install it right away using Ubuntu mainline builds.

In this guide, I’ll walk you through what’s new in Linux 7.0 RC2, what to expect from this development cycle, and how to install it safely on Ubuntu, Linux Mint, Kubuntu, Xubuntu, and other Ubuntu-based distributions.
