I wanted to update 2.16 to 2.17 with the installation manual for that purpose. The problem is I only got to the command git fetch origin which resultet in a timeout error obviously due to security changes on git as proposed by two forum topics by Larry Riddle and Murray Eisenberg.
Following the instructions in those posts I got a new error with git fetch origin: fatal: unable to access 'https://github.com/openwebwork/webwork2.git/': Operation timed out after 300011 milliseconds with 0 out of 0 bytes received
A third topic implies that maybe keys are necessary to do the trick. But I am not able to follow those hints as those point at the general installation of 2.16. I have no idea to tackle the time out.
