I'm using Raspbian.

I did successfully added the key and I can clone a private repo with ssh auth manually, using the command git clone [email protected]:USER/repo.git.

Here is how I set it up:

ssh-keygen -t rsa -b 4096 -C “email”
eval "$(ssh-agent -s)"
ssh-add -k ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub

However, if I try to run git clone command through a bash script, I get Permission denied (publickey).

I'm running the script as "pi", with sudo. The script starts with #! /bin/bash and whoami (on the script) returns root, instead of "pi".

Could someone help me out, please?

Thanks!

SSH attemps to read the keys from $HOME/.ssh. Since you are running as root, the script most likely fails to find anything under /home/root/.ssh.

The fix? Try sudo -E, which preserves the environment variables. For more info, consult sudo(8).

Awesome! It worked. Is there a way to set the "-E" option inside the script, so user would just run the script with "sudo ./script.sh"? Thanks!
I have sudo -E as an alias for myself. It is not recommended to elevate privileges in a script. It violates the principle of "least surprise". If this solves your problem, please mark the answer as accepted ;-)
