Trying to install openfoam from openfoam.com. following the instructions here for ubuntu 20.04: https://develop.openfoam.com/Develop...install-script


I get the following errors. I don't know if they're fatal or not. I should observe that I already have a version of openfoam installed, that from openfoam.org. ..are the two incompatible? I've seen people recommending that we use and get used to both.
