You can run this command to launch docker with your system GUI ```docker run it v $OPENLANE ROOT openLANE flow v $PDK ROOT $PDK ROOT v $PWD project e PDK ROOT=$PDK ROOT v tmp X11 unix tmp X11 unix e DISPLAY=$DISPLAY u $ id u $USER $ id g $USER efabless openlane current``` For question 1 I think that it is not normal If you are not good at building softwares you can use the docker images Just learn how to use docker

This means that you are using a wrong magic version You need magic version 8 3 124 and above I guess you are using Magic from ubuntu distribution by running sudo apt get install magic However this Magic version is too old You will have to build magic from source In addition you must reinstall your pdk using the new magic also

Just a note Building magic or any other component from source in docker is not hard 1 `cd openlane docker build` 2 open `docker magic Dockerfile` and change the `ARG MAGIC COMMIT=e4bebffeb49fde401e8f531a01feb4c3ef6eb9db` line to the the revision you want to install 3 `make build magic` 4 `make merge`
