Description of problem: Trying to use chromium, but it threw this selinux alert SELinux is preventing chromium-browse from 'sys_admin' accesses on the cap_userns Unknown. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that chromium-browse should be allowed sys_admin access on the Unknown cap_userns by default.
