You can use a YUM-compatible package manager to update the base Photon OS packages, which might include security patches.

If your environment consists of a vCloud Director appliance, you can update the base Photon OS packages by using directly the YUM-compatible package manager tdnf.

Applying updates to the Photon OS does not update the vCloud Director build.


  1. Update the Photon OS packages.
    tdnf upgrade
  2. Restart the appliance.
  3. Repeat the procedure for each vCloud Director appliance.
