Can't Open AppImage (Ledger Live Desktop)

Librem 14 . . . first time ever in Linux . . . downloaded the Ledger Live Desktop for Linux (ledger-live-desktop-2.39.2-linux-x86_64.AppImage) . . .

Changed the permissions to allow executable. File/App won’t open/run.

Double-click ---- Nothing.
Right-click–> Run -------Nothing.

Any thoughts/advice?

Thank you!~

Open it using the terminal and see what it says.

Here’s what it says:

blackbear@localhost:~$ cd Downloads
blackbear@localhost:~ / Downloads$ open ledger-live-desktop-2.39.2-linux-x86_64.AppImage

Everything outside the bug reporting is pretty Greek to me. Any advice is greatly appreciated! :slight_smile:

“Open” isn’t the command to use in Linux (sorry, I don’t know how similar apple is or isn’t). Navigate like you did and then type ./ledger… you can type the first few letters and then press Tab to complete the filename.

I see. Ok, tried ./ledger . . . and here’s what it said:

blackbear@localhost: ~ /Downloads$ ./ledger-live-desktop-2.39.2-linux-x8664.AppImage
[37910:0401/182921.135765: FATAL:] 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_ledgerj5ptyN/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap

Thoughts? Thank you!

Internet research yields the following steps, but the cause appears to be a configuration issue with your appimage.

In the terminal, type

sudo chown root chrome-sandbox

and press enter. It will ask for your password. Type it and press enter, noting here that you will not see your password being input. Then, type

chmod 4755 chrome-sandbox

And press enter. If they don’t report an error (the first one will, if either do) then you should be good. If not, a quick way to get your program running for now is to launch it in the terminal as you did, but append “–no-sandbox” to the end of the command. Only if you trust where you got it from, though.
