Issue with chrome-sandbox installing .deb file (plus workaround)

[PanderMusubi]

I found this error while installing the .deb file

/tmp# dpkg -i bchat-desktop-linux-amd64-2.7.3.deb 
Selecting previously unselected package bchat-desktop.
(Reading database ... 435820 files and directories currently installed.)

I noted, that in /opt/Beldex Electron Wallet

there is however

More errors: when running bchat-desktop I get

[5741:0217/171139.472759:FATAL:zygote_host_impl_linux.cc(127)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/main/docs/linux/suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.
Trace/breakpoint trap (core dumped)

This can be fixed by

sudo su
cd /usr/bin
ln -s /opt/BChat/bchat-desktop-bi

However, this leads to the following error:

[5793:0217/171208.748685:FATAL:zygote_host_impl_linux.cc(127)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/main/docs/linux/suid_sandbox_development.md for more information on developing with the SUID sandbox.

It still runs with bchat-desktop --no-sanbox. To fix it properly, do copy the missing sandbox file with

sudo cp -a /opt/Beldex Electron Wallet/chrome-sandbox /opt/BChat/

then bchat-desktop works properly.
