utils.sw.install gives int() argument must be a string, a bytes-like object or a number, not 'NoneType'

[Aaron-MJohn]

I am trying to upgrade the EX2300 with 48 POE+ switch using below code. I don't set any time out parameters in install function. Everything is using the default value.

with Device(host=hostname, user=junos_username, passwd=junos_password) as dev:
        print("Connecting to {}".format(hostname))
        if dev.connected:
            print("Device connected")
            sw = SW(dev)`
            ok = sw.install(
                package=firware_update_files,
                progress=my_progress,
                no_copy=True,
                validate=False,
                cleanfs=True,
            )

I get this exception

192.168.1.2:request-package-checks-pending-install rpc is not supported on given device

getting the following error for device timeout as well , when using version 2.6.4 , version 2.6.3 works correctly,

Python code:
rpc = dev.rpc.get_interface_information(dev_timeout=360, level_extra='descriptions')

Error below for version 2.6.4:

Hi,

Please try with option dev.timeout .

from jnpr.junos import Device
from lxml import etree

dev = Device(host='xx.xx.xx.xx', user='xyz', password='xyz', gather_facts=False)
dev.open()
dev.timeout = 360
op = dev.rpc.get_interface_information(dev_timeout=360)
print (etree.tostring(op))
dev.close()

Thanks & Regards
Chidanand

Yes setting device.timeout solved the issue. Thanks

I got the same issue and I had to pass the conn_open_timeout parameter to the call to Device in my case to fix the issue.

It seems to me that the culprit, at least in my case, is this commit 84fe8c6 because it uses None as default value for:

self._conn_open_timeout = kvargs.get('conn_open_timeout', None)

that is later used as a value for the timeout parameter inside open() at line 1312:

timeout=self._conn_open_timeout,

Issue fixed via commit #1192

Thanks @chidanandpujar . I was also getting it from junos salt-proxy when trying to apply a Salt state.
