# 1/ check for previous keys (should not exists before the first time)

cd ~/.ssh #check for already existing pair of id_x and id_x.pub (id_rsa/id_edxxx/...)

​

# 2/ generate keys (if you dont have any) - pick one

#rsa

ssh-keygen -o

#ed algorithm (recommended)

ssh-keygen -t ed25519 -C you@mail.com

​

# 3/ add the key to the shh-agent

eval "$(ssh-agent -s)" #if the agent is running, it should return something like Agent pid 18544

sh-add ~/.ssh/id_ed25519 #or: ssh-add ~/.ssh/id_rsa

​

# 4/ copy the public key

cat ~/.ssh/id_ed25519.pub #or: cat ~/.ssh/id_rsa.pub

# copy all: ssh-ed25510...... you@mail.com or ssh-rsa....... you@mail.com

​

# 5/ past it to the github

# login - profile prefferences - ssh and gpg keys - new SSH key and paste 4/

​

# 6/ verify

ssh -v git@github.com

# if you got the following error: 

# The authenticity of host 'github.com (ip)' can't be established.

# execute the following command and try again:

ssh-keyscan github.com >> ~/.ssh/known_hosts

# on ubuntu you don't need to use `eval $(ssh-agent -s)` anymore

# just generate the key and put it into ~/.ssh

# copy the .pub key to github and you should be good to go

​

ssh-keygen -t ed25519 -C your@git.email.here

cat ~/.ssh/id_ed25519.pub # if you saved it somewhere else, change this

​

# copy the output then go to github > settings > ssh and gpg keys > new ssh key

# paste the output there and save.

​

# it should work now, if it doesn't and says you don't have permissions,

# double check it and if all else fails:

# add `eval $(ssh-agent -s)` to /etc/profile or ~/.bashrc

# From SO:

# > /etc/profile is global for all users. 

# > ~/.bashrc is per user login...

​

# But AGAIN, you shouldn't need to do this, the ssh keys should just work by default

# at least in ubuntu
