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.

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

Hi, maybe you can try to replace the link "[email protected]: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 [email protected]: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
