Hi, an update. I purged all the old files and directories and started fresh. This time I crashed with an only slightly different error:

mongodb 3.4.10 installation successful.
Completed.
Completed dependency check.

************ CRYOSPARC MASTER INSTALLATION COMPLETE **************

CryoSPARC System master has now been installed.
Add bin directory to your ~/.bashrc ?

  1. Yes
  2. No
    #? 1

The following lines were appended to your ~/.bashrc:
export PATH=/home/cryosparc_user/software/cryosparc2_master/bin:$PATH

************ CRYOSPARC SYSTEM: STANDALONE INSTALLER **************

The installer will now download, install and connect the worker
package on this machine. The worker package will allow cryoSPARC
to run compute jobs.

CryoSPARC is already running.
If you would like to restart, use cryosparcm restart

Hi @frostythebiochemist,

Can you try following the post I’ve linked to below, and then reinstall cryoSPARC?
