Perhaps do a "sudo apt-get update" (updates the local resources of apt, not the packages themselves) so that when you do a "apt search" or "show" in the future it has something to show?
What does configuring IDE things have to do with Windows? Wouldn't IntelliJ have the same reasonable defaults on Linux and macOS? Or is it a different product somehow (haven't used it myself.)
You'll never see that time again.
