Unable to run AppImage or install on Ubuntu 24.04.

[imthenachoman]

• Etcher version: N/A
• Operating system and architecture: Ubuntu 24.04 x64
• Image flashed: N/A
• What do you think should have happened: It should run/install
• What happened: Error
• Do you see any meaningful error information in the DevTools? N/A

I have tried both the AppImage and installing the deb file but I'm getting an error both ways. I am not sure what to do?

username@hostname:~/Downloads$ chmod +x balenaEtcher-1.19.21-x64.AppImage 

username@hostname:~/Downloads$ ./balenaEtcher-1.19.21-x64.AppImage

Stick to the app image, DO NOT USE SUDO,
./balenaEtcher-1.19.21-x64.AppImage --no-sandbox
IF that does't work, downgrade and you get an error when loading the ISO, switch to a stable version: V1.17., It works for me.

Edit: This solution might work, its not recommended, but balena etcher is a VERY critical peice of tech, and there REALLY shouldn't be issues especially with (I think) the only software you can use to flash a USB.

Edit2: I keep getting off topic, and my responces aren't professional, but its enough to hopefully enough to solve your issue, also your issue is NOT because you are on 24.04, it does the same on 23.10, You probably shouldn't use anything earlier, but etcher should still have support so people can upgrade, although you dont even need a usb to install an OS, you can write the install media to your hard drive.

Thanks. Let me try an earlier version.

I have same issue on Ubuntu 24.
I even tried to install it via .deb but It says I have dependency problems and can't seem to install it.
