Unable to Install Newer Version of protobuf Package Due to Write Access Issue on CVMFS

The current issue involves setting up python3.9.14 and ROOT 6.26.08 while also utilizing centrally hosted python packages from cvmfs. Specifically, the issue concerns the protobuf package hosted on cvmfs, which is outdated and incompatible with onnx. skl2onnx requires a newer version of protobuf, but attempts to install it fails due to a lack of write access to the corresponding cvmfs directory.

To resolve this issue, an alternative solution must be identified that enables the installation of the required version of protobuf.
