perfSONAR User Q&A and Other Discussion

[<>]

Hi All,

 

On the second of august (02/08/2018) an update to the package “python-djangorestframework-filters” was released which has broken Esmond on my toolkit nodes.

 

Looks like someone packaged the latest version of this library and uploaded it to the perfsonar debian repo. Perhaps it was meant to be bundled with an upgrade to Esmond as well?

 

The upgrade:

 

Start-Date: 2018-08-02  06:39:47

Commandline: /usr/bin/unattended-upgrade

Upgrade: python-djangorestframework-filters:amd64 (0.6.0-2, 0.10.2-2)

End-Date: 2018-08-02  06:39:48

 

The problem:

 

2018-08-09 12:27:43,414 [ERROR] /usr/lib/python2.7/dist-packages/django/core/handlers/base.py: Internal Server Error: /esmond/perfsonar/archive/

  File "/usr/lib/python2.7/dist-packages/rest_framework/settings.py", line 164, in import_from_string

    raise ImportError(msg)

ImportError: Could not import 'rest_framework_filters.backends.DjangoFilterBackend' for API setting 'DEFAULT_FILTER_BACKENDS'. ImportError: cannot import name rest_framework.

 

 

Running apt upgrade produces no other packages available for upgrade. Reverting python-djangorestframework-filters to the previous version resolves the issue.

 

Cheers

Adam
