I've downloaded the linux 64bit binaries from cefbuild.com (both trunk 3.2217.1915, and 2171.1902) and built the examples using the build.sh script. Running cefclient from out/Release on both versions results in this error
The setuid sandbox is not running as root. Common causes:
* An unprivileged process using ptrace on it, like a debugger.
* A parent process set prctl(PR_SET_NO_NEW_PRIVS, ...)
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
The chrome-sandbox binary has the correct permissions -rwsr-xr-x 2 root root 19824 Nov 19 11:47 chrome-sandbox
What am I doing wrong ?
