How to run and/or install AppImage on Ubuntu #8440

Open d33p-dev opened 1 month ago

d33p-dev commented 1 month ago

My versions: "electron": "^31.0.2", "electron-builder": "^24.13.3", "electron-vite": "^2.3.0",

Node version: v18.19.1

Target: Linux x64

ISSUE When I run the AppImage (Ubuntu 24.04 KDE Plasma 5.27) I get the following error. I gave my user account rwx persmissions to the "appForLinux.AppImage" file.

[30783:0831/200557.279232: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_deskto9XlUHg/chrome-sandbox is owned by root and has mode 4755. Trace/breakpoint trap (core dumped)

Is this an error with my (limited) understanding of how to run an AppImage on Ubuntu or does this error indicate the packaging is bad/corrupt with Electron Builder?

I'm more of a Windows/Mac developer. Should I install the Snap or .deb version of the test app built I with Electron Builder? I thought it was straightforward to just run any AppImage on Ubuntu. But, maybe I should install the electron app some other way? If so, what would that command look like to install a Linux app built with Electron Builder?

I use "apt install" a lot... But, I'm new to Linux dev so I'm not sure what my other options are to test an Electron app on Linux. I can run the app just fine from VSCode on Ubuntu. And it works but how do I actually install it and run it?

Thanks

This is what I get when I run with sudo:

[0831/201755.141164:FATAL:electron_main_delegate.cc(295)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180. Trace/breakpoint trap

It's an issue with a security setting in Ubuntu 24.04 that affects pretty much all electron apps. See more details here: https://ubuntu.com/blog/ubuntu-23-10-restricted-unprivileged-user-namespaces

I was able to install and run the .deb package on Ubuntu with apt install ./app.deb. It ran fine. I'll do more testing. But, I guess this limits me to only Debian and Ubuntu? As I learn more, I'll post again. Thanks for the link

When installing the deb which needs root, the chrome-sandbox is suid root, so it doesn't have that problem.

This is really an Electron issue, but the maintainers haven't shown any interest in even commenting on it: https://github.com/electron/electron/issues/42510

@mmaietta I wonder if you have any thoughts on how this might be approached? Is there anything we could do at build time? Otherwise, any thoughts on how a script might help to resolve this? The core problem is that even if you want to make an exception for a single AppImage in a safe way, the way they're mounted to the filesystem at random paths seemingly makes that impossible.
