Command terminated by signal 9 can mean you ran out of memory. I would try allocating more memory to the VM. But you may still run out of memory depending upon what is available on your machine.

If you do not have to use 7.1.1 and can switch to using the newer 7.3.2 release, then for Ubuntu 20, we have a .deb file installer (https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.3.2/freesurfer_ubuntu20-7.3.2_amd64.deb) or a tar archive (https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.3.2/freesurfer-linux-ubuntu20_amd64-7.3.2.tar..gz) which you try. I would uninstall 7.1.1 if you are going to use 7..3.2 though. Again, that may not help if available memory is the issue.

External Email - Use Caution

Dear Free Surfer Development Team.

I am using the recon -all command to compute the volume of different regions of the brain. I am running the free surfer version freesurfer-linux-centos7_x86_64-7.1.1-20200723 on Ubuntu 20.4 installed on a virtual box. I am getting the following errors and the log file is also attached with this email.
ERROR: mri_ca_register with non-zero status 137
Your timely response would be highly appreciated.
