perfSONAR User Q&A and Other Discussion

[Antoine Delvaux <>]

Hello Adam,

Yes, you're correct.  Preparing for the upcoming 4.1 release an updated 
python-djangorestframework-filters package got wrongly published to the 
current 4.0 repository.  This shouldn't have happened.

For anyone who received this updated package through the unattended-upgrade 
process, you can revert to the previous version by running this command:

apt-get install python-djangorestframework-filters=0.6.0-2

Sorry for the inconvenience caused by this issue.

Antoine.
