I would like to know if it's possible to donate money to Ubuntu.
This thread points to the Contribute page, but I can't find any link pointing me to donate money (only efforts, technical skills etc.). This is the only relevant thread found by the "Check if Already Posted" tool here.
Googling "ubuntu donate", I also found the "Desktop Questions" link, but when I define what I want to donate and click to Pay with PayPal, I get a very small text saying "You are not authorized to access this page", which seems to me like a generated, internal error.
So, is there a place where I can donate?
