No zip file generated in webinterface

[peterdekker]

When using the CLAM webinterface, it is possible to download a zip/tar.gz/bz2 archive of all the output files at the end of the pipeline. In our installation, the .tar.gz and .bz2 files work, but clicking the .zip archive link gives an error.

I looked for the error message in the httpd log file. email@address.nl is my username, peternieuw is the name of my project:

FYI, we are using a custom picclservice.wsgi, with the following contents:

#/usr/bin/env python3
import sys
import os
import site

WEBSERVICEDIR = '/vol1/lamachine/lib/python3.6/site-packages/clam/'
sys.path.append(WEBSERVICEDIR)
os.environ['PYTHONPATH'] = WEBSERVICEDIR

from picclservice import picclservice
import clam.clamservice
application = clam.clamservice.run_wsgi(picclservice)

Hmm... Is zip (and unzip) installed on the system? Could be an oversight that I didn't include explicitly in LaMachine.

[peterdekker]

Yes, that was the problem! I installed them manually, now it works. Thanks!

[proycon]

Great, made an extra issue to solve this in LaMachine itself soon too.
