AppImage fails to start on Ubuntu 24.04

On Ubuntu 24.04, the AppImage fails to start with

[279021:0916/060555.286064:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_Wagyu.Z8Pe8G/chrome-sandbox is owned by root and has mode 4755.

The workaround is to --appimage-extract, then mv squashfs-root wagyu-keygen && cd wagyu-keygen, and finally sudo chown root:root chrome-sandbox && sudo chmod 4755 chrome-sandbox. It can then be started with ./wagyukeygen

The solution may be to have the right ownership and permissions for chrome-sandbox in the AppImage as distributed.

Good catch. Thanks. Let's explore how to fix this.

This might get fixed in Noble instead. I say monitor and do nothing for now
