Can a failed download be resumed without having to redownload every package?

I was downloading Android Studio flatpack on ChromeOS Linux Beta. It finished downloading the 1st(500MB) of 5 packages then began installing.

After failing Terminal reported:

Error: Flatpak system operation Deploy not allowed for user
error: Failed to install org.freedesktop.Sdk: Flatpak system operation Deploy not allowed for user

I realize that I should have run as sudo.
Is there anyway to Restart download/install without redownloading the 1st pkg?
