Git line ending errors

When ever I'm commiting something to git it gives me the warning

"The file will have its original line endings in your working directory"

How can I avoid this?

My setup is a Linux Debian VM (VirtualBox) hosted on a Windows 10 machine. I develop in PHPStorm from my Windows and all files are in a shared folder that the VM has access to. I commit my files from SSH on my VM.
