remove php8:

//If using zsh and having problems with the command above like:  'zsh: no matches found: php8.*'

Solution:
zsh, unlike bash, has a different glob/wildcard/expansion system, so it works differently so php*might not work as you expect.
So are instead of sudo apt-get remove php*, you could:

    Quote it:

    sudo apt-get remove "php*"
    
    Or Bash it:

    bash -c "sudo apt-get remove php*"
