Most likely you need to configure your SUID sandbox correctly

Answer 1

This error message...

NaCl helper process running without a sandbox!
Most likely you need to configure your SUID sandbox correctly

...implies that you have no setuid sandbox in your system, hence the program was unable to initiate/spawn a new Browsing Context ie Chrome Browser session.

Solution

As you are seeing the error even with configuring --no-sandbox and --disable-setuid-sandbox , as per the documentation in Linux SUID Sandbox Development google-chrome needs a SUID helper binary to turn on the sandbox on Linux. In majority of the cases you can install the proper sandbox for you using the command:

build/update-linux-sandbox.sh

This program will install the proper sandbox for you in /usr/local/sbin and tell you to update your .bashrc if required.

However, there can be some exceptions as an example, if your setuid binary is out of date, you will get messages such as:

Running without the SUID sandbox! 

Or

The setuid sandbox provides API version X, but you need Y
You are using a wrong version of the setuid binary!

In these cases, you need to:

• Build chrome_sandbox whenever you build chrome ( ninja -C xxx chrome chrome_sandbox instead of ninja -C xxx chrome )

• After building, execute update-linux-sandbox.sh .

   # needed if you build on NFS! sudo cp out/Debug/chrome_sandbox /usr/local/sbin/chrome-devel-sandbox sudo chown root:root /usr/local/sbin/chrome-devel-sandbox sudo chmod 4755 /usr/local/sbin/chrome-devel-sandbox

• Finally, you have to include the following line in your ~/.bashrc (or .zshenv ):

   export CHROME_DEVEL_SANDBOX=/usr/local/sbin/chrome-devel-sandbox

Answer 2

There were some missing dependencies that caused this issue ( https://www.centos.org/forums/viewtopic.php?t=60908&start=10 )

yum install liberation-mono-fonts liberation-narrow-fonts liberation-sans-fonts liberation-serif-fonts

Installing above packages solved the problem!

Hope it helps.
