'>' not supported between instances of 'NoneType' and 'NoneType'

[ginsm]

I'm having an issue when client.py tries to compare target_meta.version and self.current_archive.version (here). I'm pretty lost as I am setting the version as far as I'm aware? I largely used this repo and these examples to try and figure everything out.

Here are the files pertaining to the repository side: Repo Settings Repo Init Repo Add bundle

And here are the files pertaining to the client side: Client Settings Client Init

And here are the steps I'm taking:

1. Initialize the repo.
2. Build the app (ensuring only one bundle is in the dist dir).
3. Add the bundle to the repo.
4. Start the server.
5. Start the app.

Here's some logs that might help:

It appears to be trying to find 2.root.json which doesn't exist? This occurs when I run either the bundled app or dev app. Any help would be greatly appreciated, thanks! :)

@ginsm Thanks for taking an interest in tufup. Could you please edit your question to include the full error and server log as text, instead of linking to pastebin?

... it appears to be trying to find 2.root.json which doesn't exist?

python-tuf always tries to download a new version of root.json. That's normal. See TUF client workflow.

@ginsm This is probably caused by the whitespace in your APP_NAME.

Here's how tufup parses the version from the filename:

r'^(?P<name>[\w-]+)-(?P<version>.+)(?P<suffix>\.tar\.gz|\.patch)$'

Done and thanks for the info!

Yup, that seems to have resolved the issue. Thanks for the quick response! :grin:
