when running “git clone [https://gitlab.kitware.com/paraview/paraview.git](https://gitlab.kitware.com/paraview/paraview.git)” on a recent version of paraview: “error: unable to create file Clients/ParaView/Testing/Data/Baseline/.ExternalData\_SHA512\_666010fefb7a8a9f3d15a5d7cba039033490b583eaed34bdd852cf989f836f07104f050c2e6be9d8467a45cab066c08f78cdf499681436098f6a09fb3dfbd567: File name too long”  
I’m guessing this is hitting the character limit on ext4. Is this a bug? Any workaround? ubuntu20.04.
