Hi,
I encountered the following error while installing cryoSPARC V2 on an Ubuntu 16.04 machine:
An unexpected error has occurred.

Turns out the culprit is /home/cina/.conda/envs/ which was already existing on my environment (because of crYOLO apparently)
Deleting the whole /home/cina/.conda/ directory did the trick for me, and now I was finally able to install cryoSPARC V2. Hope this tip is useful for others as well
