Problems with import and install in MadGraph5

Asked by Neidy Lorena Bucurú Rodríguez on 2021-05-02

Hi everyone, I am learning to use madgraph. I have arch linux, I simply installed madgraph by using the command "yay -Syu madgraph" and all was working perfectly in the instalation, but, when I run madgraph and I wanted to install pythia and Delphes, there was a error that said this,

It also does not work when I want to import another model other than the SM, for example, import model heft. This error appears

You have install MG5aMC on a read-only partition.
This will indeed create issue if you want to install additional module and/or add new model.

So i would suggest to move the directory to a writable location to solve all those problems.
