Hello everyone!

Currently working on the “Making simple inter-canister calls” tutorial, I found that the `git clone git@github.com:dfinity-lab/linkedup.git` command didn’t works for me.

I got the following message:

> Cloning into ‘linkedup’…  
> The authenticity of host ‘[github.com](http://github.com) (140.82.121.4)’ can’t be established.  
> RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.  
> Are you sure you want to continue connecting (yes/no/[fingerprint])? y  
> Please type ‘yes’, ‘no’ or the fingerprint: yes  
> Warning: Permanently added ‘[github.com](http://github.com),140.82.121.4’ (RSA) to the list of known hosts.  
> [git@github.com](mailto:git@github.com): Permission denied (publickey).  
> fatal: Could not read from remote repository.

However, I found a workaround by copy pasting the link from the GitHub repository: `git clone https://github.com/dfinity-lab/linkedup.git`.

This is just for your information! 🙂 Honestly, once I found the solution I didn’t go further.

Have a nice day (or night)!
