github ssh key Key is invalid. Ensure you've copied the file correctly解决办法

标签：

此错误出现原因是：在github上添加新key时，不正确到拷贝了~/.ssh/id_rsa.pub内容所致。一般发生在linux下，因为windows下用notepa++打开这个文件并复制一般是没有问题的，而linux下使用vim打开再复制就会因为vim添加了回车而导致key添加失败。解决办法是：使用cat命令将.ssh/id_rsa.pub内容输出到终端，再拷贝。

Check for SSH keys

ls -al ~/.ssh
# Lists the files in your .ssh directory, if they exist

Generate a new SSH key

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
# Creates a new ssh key, using the provided email as a label
# Generating public/private rsa key pair.

Enter file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]

Enter passphrase (empty for no passphrase): [Type a passphrase]
# Enter same passphrase again: [Type passphrase again]

Your identification has been saved in /Users/you/.ssh/id_rsa.
# Your public key has been saved in /Users/you/.ssh/id_rsa.pub.
# The key fingerprint is:
# 01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db your_email@example.com

Add your key to the ssh-agent

# start the ssh-agent in the background
eval "$(ssh-agent -s)"
# Agent pid 59566

ssh-add ~/.ssh/id_rsa
