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

问题

I have the following in my .git/config

  1 [core]
  2     repositoryformatversion = 0
  3     filemode = true
  4     bare = false
  5     logallrefupdates = true
  6 [remote "origin"]
  7     url = git@github.com:monajalal/instagram-scraper.git
  8     fetch = +refs/heads/*:refs/remotes/origin/*

When I am trying to push the changes to the master I get this error:

$ git push -u origin master
Permission denied (publickey).
fatal: Could not read from remote repository.

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

I have tried these both but still get error:

2150  git remote set-url origin https://github.com/monajalal/instagram-scraper.git
 2154  git remote set-url origin git@github.com:monajalal/instagram-scraper.git

If you did not properly setup your ssh key with GitHub, you can at least try with https (which you mentioned):

git remote set-url origin https://github.com/monajalal/instagram-scraper.git

That will ask for your username (monajalal)/password of your GitHub account.

That will work because you own that repository, meaning you have the right to push.
Make sure you have made a commit locally in order to push.

git add .
git commit -m "new commit"

git push -u origin master

The fact that you might be forced to do a git push -f means the destination (the remote GitHub repo) is not empty but includes commits of its own (typically, a README.md or a LICENSE file)

In that case, it is best, with Git 2.9 or more, to do:

git config --global pull.rebase true
git config --global rebase.autoStash true

Then

git pull

That will replay your local commits on top of those present in (and fetched form) the GitHub repo.

Then a simple git push -u origin master would work. No need to force push your history.

Possibly not the best solution but considering there was nothing in the repository I had created in github I used the following command and it worked out:

git push -f origin master
