Application crashes on startup

[shanept]

Hi there,

I am on ubuntu 24.04. I just downloaded Backslash 0.2.2 from GitHub. As soon as I started it, I got a crash with SIGTRAP.
I then ran it in terminal and got the following error:

shane@shane-ubuntu-lt:~/Downloads$ backslash
[6160:0915/201456.942267:FATAL:setuid_sandbox_host.cc(163)] 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 /opt/backslash/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap (core dumped)

So I set the chrome-sandbox file as suggested in the output:

Update for version 0.2.2 is not available (latest version: 0.2.2, downgrade is disallowed).

As you can see from the logs, it now runs fine. I'm not familiar with Electron, whether this is a check run before it hands over to the application... However perhaps this may be something you could either handle with the application or with the package manager. It is working perfectly for me now.

Cheers, looking forward to playing around with Backslash!

Kind regards
