Hi, I’m interested whether there is a way to get APT repo download stats of all packages, not just the few top packages mentioned on [metrics.ros.org](http://metrics.ros.org). I know this has been discussed before ([Data on most popular ROS packages - ROS General - Open Robotics Discourse](http://discourse.ros.org/t/data-on-most-popular-ros-packages/13591)), but with no resolution. @DLu managed to put together the full report once, so I wonder if it’s possible to reproduce it on newer data. I know there are several mirrors out of control of Open Robotics, but even stats from the main APT repo would be interesting.

I’m not sure whether e.g. crawling data like [Statistics for packages.ros.org (2022-02) - urldetail](https://awstats.osuosl.org/reports/packages.ros.org/2022/02/awstats.packages.ros.org.urldetail.html) would lead to the correct numbers. I’d expect that when a package is updated, there should be at least as many downloads as there are mirrors, but I found packages where this doesn’t hold, so I’m confused about what these numbers mean…

The full report was a result of crawling and parsing the [OSU data](https://github.com/DLu/ros_metrics/blob/main/ros_metrics/packages.py#L14). It’s by no means a perfect measure of overall usage, but I believe it to be an accurate measurement of downloads.

Great, thanks! I’ve run the analysis for ROS1 packages now, and here are the results: [Number of total \*.deb package downloads of all released ROS 1 packages (Melodic + Noetic) · GitHub](https://gist.github.com/peci1/7a8825c0a57ecb849481c67880e9673e) .

Please note this metric tends to give advantage to packages with more built versions, as each download of any version of the package counts.

Interesting that the [“deprecated”](http://wiki.ros.org/tf2/Migration) `tf` package has the second highest number of downloads 😄.

My guess - `tf.transformations`. That’s just the easiest reachable library for working with quaternions in Python. My second guess - people often do not check `package.xml` for removals of dependencies…
