Strikes me that the download is bad. Try the download again.
Then try using the blue square icon with the green + sign in it on the far right side in the screenshot to install the Extension Pack, instead of using the command line.

While ensuring that the Extension Pack matches the Virtualbox version is required, this error seems more to indicate that Virtualbox itself is having trouble on the host. (Unless you had a further error message fingering the Extension Pack as the cause for the abort).
I may be wrong, I'm no Linux guru. But Virtualbox has prerequisites for Linux, see
https://www.virtualbox.org/manual/ch02. ... nux-prereq. And if you've changed the host OS you might need to uninstall Virtualbox, run the prerequisites again, then reinstall Virtualbox.
