[Freesurfer] Error running "Test your FreeSurfer Installation"

External Email - Use Caution

I was trying to run the command: recon-all -s bert -all

It ran for hours, but finally output the following:

writing Gaussian curvature to ./lh.white.preaparc.K...done. writing mean curvature to ./lh.white.preaparc.H...done. rm -f lh.white.H ln -s lh.white.preaparc.H lh.white.H ln: failed to create symbolic link 'lh.white.H': Function not implemented Linux hypatia 4.15.0-66-generic #75-Ubuntu SMP Tue Oct 1 05:24:09 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
