"ConnectionType" is unknown import symbol

[Benik3]

Hello.

I'm new to python and I'm trying to use this module. I successfully installed it in venv under Visual Studio Code, but I'm not able to get the block example list-connections.py code to work. I get error "ConnectionType" is unknown import symboland Cannot access member "connection_profile" for type "NetworkConnectionSettings" Member "connection_profile" is unknown.

I'm using Ubuntu 22.04 with Python 3.10.6. Am I missing something?

Hello,

Most likely issue is that you installed version 1.1.0 from PyPI but the new examples require version 2.0

There is an 2.0RC1 version on PyPI but it must be installed explicitly.

./venv/bin/pip install sdbus-networkmanager==2.0rc1

[Benik3]

You are right, pip automatically installed version 1.1.0. After forcing installation the 2.0RC1 the errors are gone. Thanks! But it looks like the example didn't run fully successfully:

You probably need this commit 457949f745db8a45f81ac9e9970e45905c416bdc . It makes the settings class backwards and forwards compatible. It is more recent than 0.8RC1 version.

Hmm I tried to uninstall the pip version and install master version from git, but I ended even with not known sdbus_block.networkmanager. I will try to continue tomorrow :)

[igo95862]

I will probably release 2.0.0 this weekend. (it will include that commit)

[Benik3]

I finally got it solved. Before I installed the package using setup.py, which made just .egg. After correct install using pip from master branch, the example works fine :)

[igo95862]

@Benik3 I did not have enough time to create 2.0.0 release this weekend.

However, I did upload the 2.0RC2 version to PyPI: https://pypi.org/project/sdbus-networkmanager/2.0rc2/

It should contain the necessary commit.
