Introduction

Previously, Ukuu was a popular tool for installing the latest Linux kernels. However, it transitioned to a closed-source, paid model. Mainline, forked from Ukuu, provides a free and open-source solution.

Mainline: A Ukuu Replacement

Mainline is a graphical application designed for installing mainline kernel builds on Debian-based systems, simplifying kernel management. It displays available kernels, allowing for easy selection, installation, and removal.

Key Features

Mainline offers:

1. Kernel Listing: Downloads and displays available kernels from the Ubuntu Mainline PPA.
2. Kernel Management: Provides a GUI and CLI for installing and uninstalling kernels, including associated packages.
3. Verification: Verifies downloaded .deb files using SHA256 checksums.
4. Notifications (Optional): Alerts users to new kernel releases.

Installing Mainline

You can install Mainline via PPA or by compiling from source.

Using the PPA:

1. Add the PPA: sudo add-apt-repository ppa:cappelikan/ppa
2. Update: sudo apt update
3. Install: sudo apt install mainline

Compiling from Source:

1. Install dependencies: sudo apt install libgee-0.8-dev libjson-glib-dev libvte-2.91-dev valac aria2 lsb-release make gettext dpkg-dev
2. Clone the repository: git clone https://github.com/bkw777/mainline.git
3. Build: Navigate to the directory and run make then sudo make install.

Launching Mainline

Mainline is typically found in your application menu under "System" or a similar category.

Understanding the Mainline Interface

Mainline's interface features columns for Kernels, Lock status, Status, Notes, and function buttons.

• Kernels: Lists available and installed kernels.
• Locking/Pinning: Allows whitelisting/blacklisting kernels, preventing accidental removal or installation. Locked kernels are ignored by install/uninstall commands.
• Status: Shows the kernel's status (installed, running).
• Notes: Allows adding custom notes to individual kernels.
• Function Buttons: Provides buttons for installation, uninstallation, viewing PPA information, uninstalling old kernels, reloading the kernel list, accessing settings, viewing about information, and exiting.
• Sorting: Columns are sortable for easier management.

Installing the Latest Kernel

Select a kernel and click "Install." Reboot to use the new kernel.

Uninstalling a Kernel

Select a kernel and click "Uninstall" or use "Uninstall Old" to remove older kernels.
