The package is Adobe Acrobat DC-20.006.20034.pkg going to Adobe Acrobat DC-20.006.20042.pkg

This is the first time I've had issues with Acrobat in this regard. Maybe something is different about the way that version numbers are interpreted in the new version of jss_helper?

It looks like it's the call to LooseVersion (packaging.version import parse as LooseVersion) that's modifying the string. I tweaked get_newest_package() to print out version before and after calling LooseVersion:

`def get_newest_pkg(options):
"""Get the newest package from a list of a packages.

Args:
    options: List of package names.

Returns: Either the newest package name or None. Package names
    must be in some format that get_package_info() can extract a
    version number.
"""
versions = {get_package_info(package)[1]: package for package
            in options if get_package_info(package)[1]}
if versions:
    for version in versions:
        print(f"Before LooseVersion: {version}")
        print(f"After LooseVersion: {LooseVersion(version)}")

    # newest = max([LooseVersion(version) for version in versions])
    # result = versions[str(newest)]
    result = None
else:
    result = None

return result`

And I got the following:

me@namaste jss_helper % ./jss_helper promote "Microsoft Teams"

 2: Microsoft_Teams_1.00.304460.pkg
 3: Microsoft_Teams_1.00.308663.pkg

Because version has been changed it's then not a key in versions. From doing a bit of reading it seems that packaging.version.parse splits the string on "." and then converts to int. At that point 00 becomes 0 and version is now not a key in the versions dict.

Not sure how that can be fixed though.

I may be able to use APLooseVersion given that we already pretty much have a dependency on AutoPkg being installed to use Spruce anyway. APLooseVersion behaves closer to what LooseVersion did in python 2. I'll give that a go when I get a chance.

Thanks Graham, your work is much appreciated.

This issue persists on the general 2.2.0 release:

Is this the same problem as the adobe issue from my initial bug report, or a separate one?

[krispayne]

Is there anything I can do to help this issue progress?

[grahampugh]

Are you prepared to have AutoPkg as a dependency for jss_helper?

[krispayne]

@grahampugh for me, it wouldn't be a problem. Their use is not independent in my environment

[grahampugh]

@krispayne please try https://github.com/jssimporter/jss_helper/releases/tag/2.2.1b1 (no package yet, but the only file that changed is jss_helper_lib/tools.py.

[krispayne]

Looks like the new tools.py lib worked in the case I was having with Zoom above.

Let me demote the adobe policy and test that one, too

[krispayne]

👍 The original adobe policy also works.

Thanks!
