I am using latest version of Ubuntu 20.04 with XFCE4 desktop environment. I've used chromium for several days and after some time chromium start to close after few seconds of execution. After that I've installed Google Chrome, and after some days, the same problem occurs.
This is the error when I launch Chrome and Chromium with terminal:
[0725/065734.139865:ERROR:nacl_helper_linux.cc(308)] NaCl helper process running without a sandbox! Most likely you need to configure your SUID sandbox correctly
What to do please help me.
