Cannot push Vue CLI app to github.io after build - Permission denied (publickey) - linux

Question

I've troubleshooted https://help.github.com/en/github/authenticating-to-github/error-permission-denied-publickey
Should the sudo command be used with Git?
I'm not using sudo together with my git commands
Check that you are connecting to the correct server
Running $ ssh -vT git#github.com makes the connection on port 22 and returns You've successfully authenticated
Always use the "git" user
I've used the set-url command to change the repo to use the SSH protocol and ssh -T git#github.com returns:

Make sure you have a key that is being used
I've created a new public/private key combination as per https://help.github.com/en/github/authenticating-to-github/adding-a-new-ssh-key-to-your-github-account
Identity added: /home/warwick/.ssh/id_rsa (myemail#gmail.com)
There is a problem here:
Starting eval "$(ssh-agent -s)" in the terminal and running ssh-add -l is returning The agent has no identities. even though I just added it?
Pushing changes made to the project src files to github does not prompt me for my password and when I check my github settings I see the key is used. So the key appears to be working
I run into Permission denied (publickey) every time I try to run build and push. I created a .deploy.sh file as per this guide on the Vue documentation and uncommented and added my username on the line intended for a github.io push https://cli.vuejs.org/guide/deployment.html#github-pages
set -e
npm run build
cd dist
git init
git add -A
git commit -m "deploy"
git push -f git#github.com:wnortier/wnortier.github.io.git master
cd -
but when I run it with sh .deploy.sh it returns

Please could anyone assist me?

Answer 1

It turns out my ssh key was setup correctly all along.
I've managed to solve the problem by running the following command: sudo chown -R $USERNAME /home/<myusername>
It allowed me to run the deploy script without [sudo].

Answer 2

Set the GIT_SSH_COMMAND in your session (as you, not root)
export GIT_SSH_COMMAND='ssh -Tv'
And run your script.
You will see the same kind of debug log you have in your question.
If not, that means the script is not running with your profile environment settings, which could explain why it works in command-line when done manually, and not through said script.
