Error when installing openclipart extension

I am getting this error when trying to install a libreoffice extension Failed to register package for vnd.sun.star.expand:$UNO_USER_PACKAGES_CACHE/uno_packages/lu8500ev8wa8.tmp_/openclipart.oxt/python
Can anyone identify what the issue might be here?
Many thanks

I had the same problem. They used to use python-uno which is no longer present, at least under Linux Mint. python-uno has been replaced with libreoffice-script-provider-python.

So if you install libreoffice-script-provider-python and then re-install the extension it should work for you.

There are a couple of things that I see. On LibreOffice Writer in 5.0 the openclipart.org link is under the Insert Media menu item and not under the Insert Image menu.

Also I have not been able to get the openclipart.org option to show up in LIbreOffice Draw, but it does show up in Write.

And I have not been able to get the the save to Gallery option to work, but it does insert the selected clipart into the Writer doc just fine.

Hope this helps if you haven’t already resolved the issue.
