Github permission denied: ssh add agent has no ide

问题:

This is my first time accessing github and I'm not experienced using console. I'm on a Macbook (using Bash). When I try to access github, I get this:

git clone [e-mail]:dhulihan/league-of-legends-data-scraper.git
Cloning into 'league-of-legends-data-scraper'...
Permission denied (publickey).
fatal: Could not read from remote repository.

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

I've tried following the instructions on Github page about Permission denied When I use ssh -vT [e-mail], I get the following:

OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011

Next, eval "$(ssh-agent -s)" returns "Agent pid 2314" However, ssh-add -l returns "The agent has no identities."

And that's where I'm stuck. I've tried googling this problem and searching here on SO. I've tried accessing files in the ssh directory, but there are none. Just a folder called Knownusers.

Can someone help me with this issue?

回答1:

Full details in this answer.

In summary, when ssh-add -l returns The agent has no identities it means that keys used by ssh (stored in files such as ~/.ssh/id_rsa, ~/.ssh/id_dsa, etc) are either missing, they are not known to the authentication agent (ssh-agent), or their permissions are set incorrectly (e.g., world writable).

If your keys are missing (i.e., you have not generated any keys), use 'ssh-keygen' (e.g., ssh-keygen -t rsa) to generate them, then use ssh-add to add them.

If keys exist but are not known to ssh-agent (e.g., they may be in a non-standard folder) use 'ssh-add' (e.g., ssh-add /path/to/my-ssh-folder/id_rsa) to add them.

See this answer if you are having trouble with ssh-add or ssh-agent.

try this:

ssh-add ~/.ssh/id_rsa

worked for me

THE 2017 ANSWER for macOs Sierra & High Sierra:

PS: most of the other answers will have you to create a new ssh key ... but you don't need to do that :)

As described in detail on https://openradar.appspot.com/27348363, macOS/OS X till Yosemite used to remember SSH keys added by command ssh-add -K <key>

So here are the 4 steps i had to take in order for it to work:

1: ssh-add ~/.ssh/PATH_TO_YOUR_SSH_PRIVATE_KEY (e.g. ~/.ssh/id_rsa)

2: Add the following in ~/.ssh/config

Host * 
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile PATH_TO_YOUR_SSH_PRIVATE_KEY (e.g. ~/.ssh/id_rsa)

3: make sure to remove any gitconfig entry that use osxkeychain helper:

4: restart your terminal for it to take effect.

I have been stucked a while on the same problem, which I eventually resolved.

My problem: I could not execute any push. I could check & see my remote (using git remote -v), but when I executed git push origin master, it returned : Permission denied (publickey). fatal: Could not read from remote repository. and so.

How I solved it :

• I generated a key using ssh-keygen -t rsa. Entering a name for the key file (when asked) was useless.
• I could then add the key (to git): ssh-add /Users/federico/.ssh/id_rsa , which successfully returned Identity added: /Users/myname/.ssh/id_rsa (/Users/myname/.ssh/id_rsa)
• I added the SSH key to github using this help page.
• Having tried all the commands in Github's 'Permission denied publickey' help page, only the ssh-add -l command worked / seemed useful (after having ran the previous steps), it successfully returned my key. The last step shows you where to check your public key on your GitHub page. And this command will help you check all your keys : ls -al ~/.ssh.

Then the push command eventually worked !

I hope this will help ! Best luck to all.

Run the following commands:

ssh-keygen -t rsa
ssh-add /Users/*yourUserNameHere*/.ssh/id_rsa** 
pbcopy < ~/.ssh/id_rsa.pub**

Go to your Github account : https://github.com/settings/profile

1) Click : SSH and GPG keys

2) New SSH Key and Past it there

3) Add SSH Key

Done!

回答6:

first of all you need to go in your ssh directory
for this type following command in your terminal in mac or whatever you use in window

cd ~/.ssh

now it is in the ssh
here you can find all you ssh key/files related to your all projects. now, type the following command to show you if any ssh key available

ls

this will show you all available ssh, in my case there were two
now, you will need to start an agent to add a ssh in it. For this type following command

eval "$(ssh-agent -s)"

now last but not least you will add a ssh in this agent type following command

ssh-add ~/.ssh/your-ssh

replace

replace your-ssh with your ssh file name which you got a list form second step ls command

回答7:

This could cause for any new terminal, the agent id is different. You need to add the Private key for the agent

$ ssh-add <path to your private key>

回答8:

One additional element that I realized is that typically .ssh folder is created in your root folder in Mac OS X /Users/. If you try to use ssh -vT [e-mail] from another folder it will give you an error even if you had added the correct key.

You need to add the key again (ssh-add 'correct path to id_rsa') from the current folder to authenticate successfully (assuming that you have already uploaded the key to your profile in Git)

回答9:

After struggling for long I was finally able to resolve this issue on Windows, For me the User env variable GIT_SSH was set to point to

"C:\Program Files(x86)\WinScp\PuTTY\plink.exe"

which was installed along with WinScp. I changed the pointing to use default ssh.exe which comes with git-scm "C:\Program Files\Git\usr\bin\ssh.exe"

Steps for BitBucket:

if you dont want to generate new key, SKIP ssh-keygen

ssh-keygen -t rsa 

Copy the public key to clipboard:

clip < ~/.ssh/id_rsa.pub

Login to Bit Bucket: Go to View Profile -> Settings -> SSH Keys (In Security tab) Click Add Key, Paste the key in the box, add a descriptive title

Go back to Git Bash :

ssh-add -l

You should get :

2048 SHA256:5zabdekjjjaalajafjLIa3Gl/k832A /c/Users/username/.ssh/id_rsa (RSA)

Now: git pull should work

回答11:

This worked for me:
chmod 700 .ssh chmod 600 .ssh/id_rsa chmod 644 .ssh/id_rsa.pub

Then, type this: ssh-add ~/.ssh/id_rsa
