Errors in Ubuntu 24.04

namespace stuff might affect us depending on how it gets installed

On a fresh Ubuntu 24.04:

• Snap Store: Works
• Apt repository: Works
• Flathub: Works
• AppImage: Had to manually apt install libfuse2t64. Works when started from Files but not Terminal.
• tar.gz: Works when started from Files but not Terminal.

No idea why it's different in Files or Terminal.

The error looks like:

[3592:0426/221330.463740: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 /home/vmuser/Downloads/TurboWarp-linux-x64-1.11.1/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

Temporary fix (until reboot) is to run sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0 (enables using namespaces without root; has a history of security problems) or start app with --no-sandbox (disables Chromium sandbox; extensions still can't access things like Node.js directly but in theory a V8 security bug could let them escape without needing to also escape a reasonably secure sandbox)

This is an upstream problem that other projects also have so I'll just wait and see what other projects do in response electron/electron#41066
