PyEz jnpr.junos.utils.sw install function

[Michelle Zhang]

Hi,

I am doing a project in PyEz, but I encountered one issue with sw.install function. The main logic of this project is to upgrade a srx box with PyEz, so the project reach out to download needed Junos version from online, store it locally and use sw.install() function followed by a sw.reboot() function to upgrade srx.  Below is a snippet of my code:

       def  install_process(dev, msg):
              print("{}:{}".format(dev.hostname, msg))

 

        sw = SW(device)
        print(path)                      # where Junos version is stored after downloading
        try:
            ok = sw.install(package=path, progress = install_progress)
        except Exception as err:
            print("Install error")
            print("err")
        If ok is True:
            print("Software installation complete, rebooting ...")
            sw.reboot()                                                             

       

The case is if I download Junos version in my program, this codes with end up with error and quit, output is like these:

Downloading now, please don't click anything
it'll automatically move on once it's done
https://..../software/junos/12.1X46-D35.1/junos-srxsme-12.1X46-D35.1-domestic.tgz.... 

 

junos/junos-srxsme-12.1X46-D35.1-domestic.tgz
Install error
proper value either package or pkg_set is missing
Traceback (most recent call last):
 line 189, in junos_auto_install
    if ok is True:
UnboundLocalError: local variable 'ok' referenced before assignment

If I run my exact same scripts with a downloaded Junos version beforehand (program will do the local storage check), it will run pretty smoothly, like these: 

Found local proper installation package
junos/junos-srxsme-12.1X46-D35.1-domestic.tgz

So any ideas or comments on how this can be improved? Or this is a bug that haven't been covered yet?

Hi Michelle,

Can you share the script part which is being used to download the package. You can unicast me too.

Thanks

Nitin Kr

Hi Nitin,

I just started to use google group and not so familiar with the functions it provided, can you tell me how to unicast you? do you mean a juniper email or something?

Best,

Michelle
