I just upgraded from ubuntu 18.04 to 20.04 and now use gcc9. I could also update fluka and flair to current versions. However, I get the following in flair:
w> Warning: Geometry Viewer not found
e> ERROR: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory
Can I please be assisted on how to get rid of this/
