Per

Answer 1

sudo chmod -R 777 folder but without any success.

That would never work, as any folder with writing right would make ssh fail immediately.

You need to make sure that:

• you have generate the ssh key pair properly:

  ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
  

(I recommend not setting a passphrase at first, at least for testing)

• the right associate with your ~/.ssh/id_rsa(.pub) are correct.
  At least:

  chmod 700 /home/<login>/.ssh
  chmod 600 /home/<login>/.ssh/authorized_keys
  

• the ssh url is correct.
  For instance, GitHub would use git@github.com:user/repo

• your ssh key is registered to your account (Example for GitHub)

Answer 2

Have you tried this command to check your key ssh -T git@github.com

Also you need to check if your remote url is added to git config correctly.
