Could not read from remote repository

Question

I have received the following error multiple times:

Could not read remote repository. Please make sure you have the correct access rights and the repo

Answer 1

if you want to push/pull any repository from local to remote(git hub)
first checkout

$ git push https://

working fine with username and passwd credential

$ git push git@

fail
Could not read remote repository. Please make sure you have the correct access rights and the repository exists.

this means you need to add id_rsa.pub to authorized_keys

goto 
$ cd /home/admin/.ssh
$ls
$vi authorized_keys
add id_rsa keys(n no of keys you can add)
