esim installation fatal error

[2112jpc]

I am following the wiki instructions at github.com/uzh-rpg/rpg_esim/wiki/Installation. I managed to install ROS without problems (I am using Ubuntu 20.04 and Noetic was recommended by the ROS site) and I installed catkin. However I am getting the below error when I get to the “Clone this repository and run vcstools” step. Any help would be appreciated.

cs@cs-l004:~/sim_ws/src$ git clone git@github.com:uzh-rpg/rpg_esim.git Cloning into 'rpg_esim'... The authenticity of host 'github.com (192.30.255.112)' can't be established.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'github.com,192.30.255.112' (ECDSA) to the list of known hosts. git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

Hi, maybe you can try to replace the link "git@github.com:uzh-rpg/rpg_esim.git" with "https://github.com/uzh-rpg/rpg_esim.git" and git clone will work.

In addition to that, you need to change the URL in "rpg_esim/dependencies.yaml" file. I've posted the contents of my modified yaml file below, just replace the contents of the original yaml file directly. I hope this helps you.

Thank you very much for the suggested fix. I won't know when I will be able to try it out but I will keep it in my notes. I will keep this issue open in case anyone else can comment on the fix.

I had a similar issue:

~/sim_ws$ git clone git@github.com:uzh-rpg/rpg_esim.git
Cloning into 'rpg_esim'...
Warning: Permanently added the ECDSA host key for IP address '140.82.121.4' to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.

Resolved by following this git tutorial. You need to create a local SSH key, add it to the SSH agent and finally copy it to your Github account to authenticate yourself.

Cheers,

Youssef
