To summarize, preview Linux build for Slicer application and associated extensions will not be available until we address this (\*)
In the meantime, thanks for your patience 🙏
(\*) _Note that we will also add regression tests to the relevant continuous integration to avoid this specific issue from happening again_
## Background
While working on updating CMake and compilers (See [1]) used on the different “factories” (aka build machine responsible to build application and extension packages), we also updated the docker images used generate the Linux packages (See [2]).
To be specific, we first updated the [dockbuild/dockbuild](https://github.com/dockbuild/dockbuild) and then updated the `slicer/buildenv-qt5-centos7:latest` image specific to Slicer and maintained at [Slicer/SlicerBuildEnvironment](https://github.com/Slicer/SlicerBuildEnvironment).
The problem is that simply bumping the python version used in the script [imagefiles/build-and-install-python.sh](https://github.com/dockbuild/dockbuild/blob/master/imagefiles/build-and-install-python.sh) was not sufficient and the python version installed in the image is lacking modules like `_ctypes` that are required to use the [slicer\_package\_manager](https://github.com/girder/slicer_package_manager#readme) python client.

Issue has been addressed:
- Image `slicer/buildenv-qt5-centos7:latest` has been updated
- Update from the linux “factory” has been manually triggered
- Download site now show the linux package is available for download (see screenshot below)
