I can't install Unity 3d via Unity Hub

I succesffuly installed Unity Hub 2.2.2 on Ubuntu 18.04. In Unity Hub, I select Unity 2019.2. I also select "Android Build Support", "Android SDK", "Open JDK" and "Unity Documentation". Unity Hub downoloads all these files completly. But when it tries to install them, it crashes. And I lose all the files. I did it twice but it's the same result.

1. How can I can I fix it?
2. Which folder must I choose to Install Unity on Ubuntu?

Thanks

Check file permissions on the destination directory. Make your user the owner with the command:

sudo chmod -R user:user /opt/unity
