ssh returns “Bad owner or permissions on ~/.ssh/config”
I needed to have rw for user only permissions on config. This fixed it. chmod 600 ~/.ssh/config As others have noted below, it could be the file owner. (upvote them!) chown $USER ~/.ssh/config If your whole folder has invalid permissions here’s a table of possible permissions: Path Permission .ssh directory (code) 0700 (drwx——) private keys … Read more
SCP Permission denied (publickey). on EC2 only when using -r flag on directories

So in your first command, you are actually asking scp to upload the .pem file itself using your default ssh key. I don’t … Read more

move_uploaded_file gives “failed to open stream: Permission denied” error
