[cubex1234]

                        I installed OpenLane in my HOME  directorie on Ubuntu 20.04 ; make test works Ok.For new design \
                        I follow  the docker openlane docs .The commandline  to  launch docker appropiate image is :                                                              

      sudo docker run -it -v $(pwd):/openLANE_flow -v $PDK_ROOT:$PDK_ROOT -e PDK_ROOT=$PDK_ROOT -u $(id -u $USER):$(id -g $USER) openlane:rc

i get this :
Unable to find image 'openlane:rc' locally
docker: Error response from daemon: pull access denied for openlane, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'

Question 1:

1. What is/refer "openlane:rc " ; If refer an overlay2 image for /var/lib/docker pls how is to be write for the command line to work.
   I can not figured out what i have to write there.###

openlane:rc is very old version.
Install latest version as per instruction from here: https://github.com/The-OpenROAD-Project/OpenLane?tab=readme-ov-file#installation-the-short-version
