Omniverse Launcher .appImage core dump on CentOS

When I try to launch the omniverse-launcher-linux.AppImage on CentOS 7.9 [Mate], I get the following:

[24014:0817/] 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_omnivei0eNv2/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

Hello @awilliams2! This looks like an issue with Linux Sandboxing. According to their documentation, this issue can happen with any program build on the top of an Electron Framework. I did a search and found 3 possible solutions that you can try.

Solution #1

If the program is not packaged in a .AppImage file, you can simply set the right permissions to the chrome-sandbox file:

cd LosslessCut-linux
sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox

Solution #2 (Probably the easiest one)

You can run the app with the --no-sandbox argument:

./LosslessCut-linux.AppImage --no-sandbox

Solution #3

Enable unprivileged access to CLONE_NEWUSER in your kernel:

sysctl kernel.unprivileged_userns_clone=1

Let me know if any of these has helped!

Hi Wendy,

Thanks for all the info. Running with --no-sandbox seems to have solved the issue for us.
