1. Add the official raspbian repo: echo "deb http://archive.raspbian.org/raspbian stretch main contrib non-free" | sudo tee /etc/apt/sources.list.d/raspi.list
2. Add the gpg key (required to download): wget https://archive.raspbian.org/raspbian.public.key -O - | sudo apt-key add -
3. Then download bash-doc: sudo apt-get update && sudo apt-get install bash-doc
This should fix the issue with dietpi-software, if you get any more errors, try seeing if the package is installed first!
