readme.md

1. Connect to your raspberry Pi with SSH
2. Install zsh : sudo apt-get update && sudo apt-get install zsh
3. Edit your passwd configuration file to tell which shell to use for user pi : sudo vim /etc/passwd and change /bin/bash and /bin/zsh
4. Reconnect to your raspberry, and check that zsh is the shell with echo $0.
5. Switch to root : sudo su
6. Install OhMyZsh : sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
7. Disconnect from your instance and reconnect it.

@InfiniteCoder01 What version of git is it using? It looks like a git error.

Try updating it.

I've reinstalled my system and it worked

You can also do step 3 as:
#chsh -i /bin/zsh
Logout of the session and then log back in it should have changed.
