Composer install not working

[norrcomm]

I am following the instructions and trying to install composer on my Ubuntu 20.04 system and it is faling.

This is the output can someone let me know if I am missing a step?

john@ut01:/var/www/passwords$ ./install_composer.sh
PHP Warning: copy(composer-setup.php): Failed to open stream: Permission denied in Command line code on line 1
PHP Warning: hash_file(composer-setup.php): Failed to open stream: No such file or directory in Command line code on line 1
Could not open input file: composer-setup.php
rm: cannot remove 'composer-setup.php': No such file or directory

I can go to my Windows computer and successfully download the .sig file but my Ubuntu box just fails to download it.
