Not enough space?

Updating your Raspberry Pi but realise that you are running out of space? When you are running sudo apt full-upgrade,  it will show you how much data will be downloaded and how much space it will take up on your SD card.

You can first check how much free disk space you have with this following command as theapt command will not do this for you:
