WORAROUND

This error seems to only impact debian-based system.
If you are impacted by that error, you can correct by yourself without waiting for the next patch release being done to address it with the command:

sed -i -e 's/rsync --delete/rsync --delete --ignore-times/g' /opt/rudder/bin/rudder-upgrade

Then, execute again the post-upgrade script:

/opt/rudder/bin/rudder-upgrade

ORIGINAL REPORT
