Describe the bug

Below is the script I am using to upgrade from 9.1.16 to 11.1.3 code:

---

from panos.firewall import Firewall

fw = Firewall("<IP of PA Firewall>", "Username of PA Firewall ", "<Password of PA Firewall") fw.software.upgrade_to_version("11.1.3")

Expected behavior

It should not present any error.
