To Reproduce Steps to reproduce the behavior:

1. Go to Settings -> Addons extensions-> Install extension from addons

2. Click on wx.metadata under wxGUI section.

3. In console tab, the following message appears:

4. g.extension extension=wx.metadata

5. Downloading precompiled GRASS Addons <wx.metadata>...

6. ERROR: canoont open URL: http://wingrass.fsv.cvut.cz/grass82/addons/grass-82.0/wx.metadata.zip

Additional context Add any other context about the problem here.

Currently wx.metadata addon is not precompiled/prebuilded on the MS Windows OS platform due bug related with incorrect GDAL library version during compilation Win GRASS GIS issue #2497, https://github.com/OSGeo/grass/issues/2288#issuecomment-1194101047, https://github.com/OSGeo/grass-addons/issues/771. Affected are other addons too.

Currently quick workaround is install this addon under GNU/Linux OS platform.

It seems owslib is missing on the buildsystem too: https://wingrass.fsv.cvut.cz/grass82/addons/grass-8.2.1/logs/wx.metadata.log Or the addon could use lazy imports of third party libraries...

Yes you are right, lazy import is the way how to solve this issue.

Looks like it's already been resolved.

No it is not resolved in the version 8.2.

It is recommended to move to the latest stable version 8.3.
