The public key needed is stored in ~/.ssh/id_rsa.pub, however the first debug message say that there is no such file or directory. I am working on the Windows Subsystem for Linux. Does someone know what the problem is?

Answer 1

Turns out there was not really a problem, I had uploaded my public key and apparently this still had to be processed on the server. Trying exactly the same the next morning worked for me.
