madgraph+pythia8 NLO+PS example failing on fedora 36

Asked by Gustavs Kehris

Hello,

I have been trying to run madgraph and pythia8 locally on fedora 36, but have encountered several issues.

For starters, the automatic madgraph installation of StdHep (as well as the python interface of LHAPDF) failed.

Hoping that pythia8 wouldn't use StdHep, I proceeded with an example usinig pythia8 despite the unsuccessful StdHep installation.

Everything seems to work fine until showering, but at this point I encounter the error:

opening /path/to/MG5_aMC_v2_9_11/my_ttbar_test/run_01_tag_1_debug.log I find:

Hi Marco,

Since creating this thread I learned that my lhapdf installation did not have write privileges to the folder where it downloads PDFs. I fixed this. Now, after executing `launch`, the final output before the run concludes is:
