Unable to install Windows and Mac build support 2018.3.2f1

I’m trying to install the Windows and Mac build support for the Linux editor using Unity Hub. Previously, using the old installer this wasn’t a problem. Now, every time the download completes I get a generic message saying unable to install Windows/Mac build support.

Is anyone else having this issue? If so let me know if you find a work around. I’d prefer to do everything from my Linux machine. Having to jump from computer to computer gets annoying very fast.

Thanks,

What distribution are you on?

Linux Mint 19.2

This is the first time I’ve had problems with Unity add-ons using this build of Mint.

Found the answer in another post. Installing 7zip-full fixes the issue.

sudo apt install p7zip-full p7zip-rar

The original post.

Correction, partially solved. I now have Windows and Linux build support but no Mac. It shows Mac support installed but it isn’t available under the build options.
