Up against ERROR 403: Forbidden when installing pythia 8

Asked by Yuchen Guo on 2020-04-27

Dear Olivier,

Starting from the day before yesterday, I always receive a 403 forbidden when installing pythia8.
I am using Ubuntu 18.04.

================================
MG5_aMC>install pythia8
You are installing 'pythia8', please cite ref(s): arXiv:1410.3012.

================================================

Is there a work around?

For example we copy the files from the HEPTools/pythia8 folder from another computer, but there is also an error about mg5amc_py8_interface.

MadGraph5Error : Histogram with run_id '0' was not found in the specified XML source.
quit
===================================

I reinstalled the mg5aMC_py8_interface, and other error show up:

======================================================
......
The version of HEPMC2 linked to Pythia8 seems not to include a static library.
This is necessary for the default compilation of MG5aMC_PY8_interface.
You can try again with the option --pythia8_makefile but HEPMC2 will need to be available at runtime.

Command "install mg5amc_py8_interface " interrupted in sub-command:
"install mg5amc_py8_interface" with error:
InvalidCmd : Installation of mg5amc_py8_interface failed.
===================================================

Please help!

Best

HI,

Your second issue is due to a configuration error when multiple version of PY8 exists.
Look at the last post of this thread:
https://bugs.launchpad.net/mg5amcnlo/+bug/1649725
on how to fix that.

Cheers,

Olivier

PS: For the py8 link, we will have to wait that their website is up again

Manfred Hampl (m-hampl) said : #2

The website is up, bit the file seems not to exist (any more).

If you look at http://home.thep.lu.se/~torbjorn/pythia8/ you will see that several file with a name line pythia(number).tgz exist, but no file pythia82.tgz

This seems to be an inconsistency between the filename in the installer and the files available on the server.

Ah i see,

Looks like pythia8 author have decided to remove that tarball.
I will check with them what need to be done.

Cheers,

Olivier
