Environment

All supported DX NetOps Virtual Network Assurance (VNA) releases

Cause

Umask was set to 0027 causing systemic permissions issues.

Resolution

Before running the installer, set umask to 0022 by issuing this command:

umask 0022

Additional Information

If there was a previous VNA installation on the server, make sure you delete the /etc/my.cnf file.  Set the bash shell to umask 0022 and then run the installer.
