What is an X509_USER_PROXY, what does it mean that it isn't set and how do I fix this error?

ROOT

So I got an error involving something I don’t understand at all:

Filename root://cms-xrd-global.cern.ch/Neither X509_USER_PROXY or X509_USER_KEY/X509_USER_CERT are set is remote, will do a copy to local path /tmp/migordon/X509_USER_CERT are set-3232313431333134.root

I was wondering what this even means and how do I fix it. Thanks.

As it seems RDF related, @eguiraud might know.

Hi,

not a RDF issue, this is an xrootd error related to remote file access. Make sure you can call TFile::Open on the input file from a SWAN Jupyter notebook. This looks like a permission issue.

Ok, I realized I had a voms-proxy-init issue and that the grid certificate I had installed was in fact a re-installation of an old, expired one. I downloaded a new one, but need help installing it in SWAN. How do I get the new certificate into SWAN?

Hi @Diracula ,

I’m glad to hear you could figure out what the problem was.
I’m afraid your last question is really for the SWAN admins :sweat_smile:

Cheers,
Enrico
