必须不断将ssh密钥删除/添加到github

Question

I've been having this strange issue. I just recently upgraded my mac to sierra and I generated a new ssh key for github.

The problem is, I add my ssh key to gihub and it works for like 15mins and then after that I get an error

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

So I end up doing

pbcopy < ~/.ssh/id_rsa.pub

And I delete the ssh key in github and add again. I have to keep doing this every 15 mins. Does anyone have any clue what the problem is?

Answer 1

This is purely Mac Sierra related, as can be read here .

Generate a new key using

ssh-keygen -l -f ~/.ssh/id_rsa.pub

If you receive a reply starting with something like 2048 SHA256 , you should be good to go. Just copy it to github.

If not, you have to run

ssh-keygen -t rsa

and do as you proposed to do. I had the same problem and Quincy's explanation helped me alot.
