Error in Weka: error in opening zip file

I am trying to use Weka 3.8 and 3.9 (tried both versions in Mac and Windows) but I can't seem to install any additional packages. It always gives the error: error in opening zip file.

I have been facing the same problem in both Windows and Mac. What worked for me was to download the packages I was interested in at https://sourceforge.net/projects/weka/files/weka-packages/ After the download, open your package manager in weka and in Unofficial select File/Url and choose the downloaded package file. After this, you just have to close and open weka again and your packages should be available. Hope this helps! V.
