GitHub Error Message - Permission denied (publickey)

Question

Anybody seen this error and know what to do?

I\'m using the terminal, I\'m in the root, the GitHub repository exists and I don\'t know what to do now.

Answer 1

tl;dr

in ~/.ssh/config put

PubkeyAcceptedKeyTypes=+ssh-dss

Scenario If you are using a version of openSSH > 7, like say on a touchbar MacBook Pro it is ssh -V
OpenSSH_7.4p1, LibreSSL 2.5.0

You also had an older Mac which originally had your key you put onto Github, it's possible that is using an id_dsa key. OpenSSH v7 doesn't put in by default the use of these DSA keys (which include this ssh-dss) , but you can still add it back by putting the following code into your ~/.ssh/config

PubkeyAcceptedKeyTypes=+ssh-dss

Source that worked for me is this Gentoo newsletter

Now you can at least use GitHub and then fix your keys to RSA.
