Found a liar

https://linux-packages.com/debian/package/zsh

sudo apt update
      ===>>>      sudo apt install zsh
NEVER,
              NEVER  
                             DO 
                                         THAT
BECAUSE:
sudo apt remove zsh
and your box doesn 't work any longer as you want it to work
Of course there are some who will do it, but please keep an other VT open to 
install zsh again to keep you box useable and you can work, not just play 
games
