Hi All, while using below script getting exception. Need your advice to rectify this. 

Script:

from jnpr.junos import Device

from jnpr.junos.utils.fs import FS

from jnpr.junos.utils.config import Config

from jnpr.junos.utils.sw import SW

from pprint import pprint

from jnpr.junos.utils.start_shell import StartShell

def myprogress(dev, report):

    print("host: %s, report: %s" % (dev.hostname, report))

Package = 'junos-install-ex-x86-64-25.1R1.108.tgz'

dev = Device(host='10.85.153.172', user='labroot', passwd='lab123')

dev.open()

sw = SW(dev)

t = '/var/tmp/' + Package

print(t)

a = sw.validate('/var/tmp/' + Package)

print(a)

Error:
