[email protected]: Permission denied (publickey,password)

Question

I google online to find the solution and tried as this link https://docs.github.com/cn/authentication/troubleshooting-ssh/error-permission-denied-publickey

But it didn't work.

1. When I type ssh -vT [email protected], the result:

2. When type ssh-add -l -E sha256 the result is same as github ssh keys

3. I tried as here https://docs.github.com/en/authentication/troubleshooting-ssh/error-permission-denied-publickey, when type eval "$(ssh-agent -s)", then typessh-add -l -E sha256 , output is The agent has no identities. when type ssh -T [email protected], the terminator ask me to input the [email protected]'s password: , either the password to login in the github website or the password to ssh-gen(actually no password) is not OK. Which password should I type here?

Agent pid 16629
➜  apollo git:(predtr) ssh-add -l -E sha256  
The agent has no identities.
➜  apollo git:(predtr) ssh-agent bash      
(base) zetlin@zetlin-HP-Z4-G4-Workstation:~/Code/github/apollo$ ssh-add ~/.ssh/id_github
Identity added: /home/zetlin/.ssh/id_github ([email protected])

Update:

4. Follow the tips, maybe the configuration is conflicting, I delete the configure files& keys files in /etc/ssh/ssh_config & known_hosts in /home/zetlin/known_hosts, then command ssh -vT [email protected], the result:

I still don't know the password

update:

5. I could git clone 'https' but not 'ssh'
