Forgive me, I am a ubuntu-newb.
I was running UbuntuStudio 19.10, and upgraded to 20.04. I want to look through the software repository, but can't find the "Software Center" discussed here: https://help.ubuntu.com/community/UbuntuStudio/FindingSoftware. I think I used it once before, because I have Rosegarden running - but now I can't find it.
Any assistance will be greatly appreciated!
