On Debian Linux distro launching Brave from the app list doesn’t launch. When trying to launch from terminal shows the following error
[978:978:0601/200121.052447:FATAL:zygote_host_impl_linux.cc(107)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/master/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.
To solve this open terminal and switch to root or a super user and type
echo 'kernel.unprivileged_userns_clone=1' > /etc/sysctl.d/00-local-userns.conf
service procps restart
