Riot-desktop does not launch

[blackpidgeon]

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/Riot/chrome-sandbox is owned by root and has mode 4755.

I have tried the tricks mentioned in #2946 with no success

Is force-nonewprivs yes set in /etc/firejail/firejail.config?

What is your firejail version? distro?

Seems to be an issue regarding Electron and not Firejail perhaps, can you try checking the permissions of that file and setting it to root and/or the workaround(s) here element-hq/element-web#10509
For Xubuntu 20.04, things work fine with the default profiles and no extra config made.
-rwsr-xr-x 1 root root 6259104 Jun 29 21:29 /opt/Riot/chrome-sandbox

riot-web version: 1.6.7
olm version: 3.1.3

@blackpidgeon Does it work with --noprofile?
BTW: It would be helpful if you put such error messages in quotes or code-blocks, since such error-messages have no "technical" things in it.

@kortewegdevries It's very likely that the file has the right permissions. (if it works without firejail we know it sure). Firejail features such as nonewprivs can "skip" the suid-bit.
