I have a desktop running Focal and a laptop running Jammy. I work with point clouds, which I look at using CloudCompare and process with programs I write. I ran one of my programs on the laptop and got a LAS file, so I ran CloudCompare and tried to open it. It refused. I copied the file to the desktop and ran CloudCompare, which opened it with no problem.
Here is the description of CloudCompare, first on Focal, then on Jammy:

Description: 3D point cloud and mesh processing software
This is a 3D point cloud (and triangular mesh) processing software. It has been
originally designed to perform comparison between two 3D points clouds (such as the ones
obtained with a laser scanner) or between a point cloud and a triangular mesh.
It relies on a specific octree structure that enables great performances in this
particular function. It was also meant to deal with huge point clouds (typically more
than 10 millions points, and up to 120 millions with 2 GB of memory)

CloudCompare on Focal is built with PDAL, which reads LAS files (and I once found a bug in PDAL by opening a malformed LAS file with CloudCompare). CloudCompare on Jammy is not, even though PDAL is available (it's called base13 instead of base9). The ones obtained with a laser scanner, mentioned in both descriptions, are usually LAS files. Why doesn't it open them, and where can I get a CloudCompare for Jammy that reads LAS files?
