I’ve created a table but couldn’t find the proper way to contribute it to the documentation, so I’ll leave it here.

Build Dependencies for Different Distributions

Notes:

• openSUSE Leap provides both WebKitGTK 4.0 and 4.1, but we use libwebkit2gtk-4_1-0.

• Fedora had only webkit2gtk4.0 up to version 39; starting from Fedora 40, webkit2gtk4.1 is available.

• On RHEL / AlmaLinux / Rocky / CentOS (8 and 9), webkit2gtk3 corresponds to ABI 4.0; 4.1 is not yet available.

• Arch Linux offers both webkit2gtk and webkit2gtk-4.1, but for the new ABI we use the latter.

Build Tags:

As a result, use the -tags webkit2_40 build tag only for RHEL-based systems.
All other distributions already support the modern version, so use -tags webkit2_41 for them.

This table reflects the current state of repositories and packages as of May 2025.

Summary, your need 3 different files for different distro

$ tree build/linux/nfpm/
