A possible solution to such an error message , is to use ssh ,to commit to your git repository , as follows .
First , start by generating your public , and private
ssh , key pairs :
# Select only one of the following commands , the # first one uses a newer algorithm , which might # not yet be supported by the client. $ ssh-keygen -t ed25519 -C "firstname.lastname@example.org" # Generate user own ssh public , and private # key pairs , using the algorithm ed25519 , # with a comment of user email . Generating public/private ed25519 key pair. Enter file in which to save the key (/Users/difyel/.ssh/id_ed25519): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /Users/difyel/.ssh/id_ed25519. Your public key has been saved in /Users/difyel/.ssh/id_ed25519.pub. The key fingerprint is: SHA256:a9JAoN2pwMcYaYxNsi0shyqGmVl0ZeG8YMV2KuQiDcw email@example.com The key s randomart image is: +--[ED25519 256]--+ |+=+.oo=. | |+E=B.Bo.. | |==Oo*.*o | |=Bo+o+.. | |Bo ...o S | |o o . | | . + | | o | | | +----[SHA256]-----+ $ ssh-keygen -t rsa -b 4096 -C "firstname.lastname@example.org" # uses the rsa algorithm with a key size of 4096 , # with a comment containing an email . Generating public/private rsa key pair. Enter file in which to save the key (/Users/difyel/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /Users/difyel/.ssh/id_rsa. Your public key has been saved in /Users/difyel/.ssh/id_rsa.pub. The key fingerprint is: SHA256:GDdMlCeNp/+xc9EuxTmSvEgaMeKc/pe/km/0Lycrr4s email@example.com The key s randomart image is: +---[RSA 4096]----+ | .o+ | | o+ + | | . += | | =.+ | | + S.o . .o.| | + ....=.o+| | . +.=o++.| | . .

This will create the following files in the
~./ssh/ folder :
$ ls -al ~/.ssh # list the content of the ~/.ssh # folder . # If the ed25519 algorithm was used to # generate keys , and the default name # was selected , then these two files # will be created . id_ed25519 id_ed25519.pub # If the rsa algorithm was used to # generate keys , and the default # name was selected , then these # files will be created . id_rsa id_rsa.pub
Copy the generated , public key to the clipboard , for example by first echoing it , and then copying it .
$ cat ~/.ssh/id_ed25519.pub # If the chosen algorithm is ed25519 . ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMa4Mrn6kaZXEsbhTQqvkFYUQN1d1exvauDut1ssD8np firstname.lastname@example.org $ cat ~/.ssh/id_rsa.pub # If the chosen algorithm was rsa . ssh-rsa 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 email@example.com
And add it to GitHub , by going to ssh and gpg keys , and creating , a new ssh key :
To change from https , to ssh , in your local computer , go to where you have stored your repository , and issue the following commands :
$ git remote -v # Check the configured protocol . origin https://github.com/mohamad-wael/tmp.git (fetch) origin https://github.com/mohamad-wael/tmp.git (push) $ git remote set-url origin firstname.lastname@example.org:mohamad-wael/tmp.git # Switch to ssh , by replacing https://github.com/ , # with email@example.com: $ git remote -v # Check the configured protocol . origin firstname.lastname@example.org:mohamad-wael/tmp.git (fetch) origin email@example.com:mohamad-wael/tmp.git (push) $ git push origin main # Push to GitHub The authenticity of host 'github.com (188.8.131.52)' can't be established. RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'github.com,184.108.40.206' (RSA) to the list of known hosts. Branch main set up to track remote branch main from origin. Everything up-to-date
To switch back to https , issue :
$ git remote set-url origin https://github.com/:mohamad-wael/tmp.git
