curl install gives error on ubuntu

[TOliverKocsis]

Hi, I tried folowing the install instructions in the readme: https://github.com/git-ecosystem/git-credential-manager/blob/release/docs/install.md#install-from-source-helper-script
I installed curl.
Then tried: $ curl -L https://aka.ms/gcm/linux-install-source.sh | sh
I get the folowing output:

EDIT:
I got it to work by sending the script to a file, give that execute permissions, then executing it.
