Connection issue during instalment Problem

Dear devs,
during the Installation-process on a standalone workstation I encountered this issue during the worker-master connection:

Connecting the cryoSPARC worker to the master…


CRYOSPARC CONNECT --------------------------------------------

Attempting to register worker cryosparc-ws to command cryosparc-ws:39002
Connecting as unix user cryosparcuser
Will register using ssh string: cryosparcuser@cryosparc-ws
If this is incorrect, you should re-run this command with the flag --sshstr

Connected to master.

Current connected workers:

Autodetecting available GPUs…
Detected 2 CUDA devices.

   0      0000:55:00.0  NVIDIA RTX A4000
   1      0000:A2:00.0  NVIDIA RTX A4000

All devices will be enabled now.
This can be changed later using --update

Traceback (most recent call last):
File “bin/connect.py”, line 228, in

AssertionError: Path /scratch/cryosparc_cache is not writable.

Master seems to be working as cryosparcm start runs into no issue. Just seems to be the connection.

Im installing on an Ubuntu 22.04 and have the CUDA 11.8 driver.

/scratch/cryosparc_cache
must exist and be writeable for the cryosparcuser Linux account. Permissions for the cryosparc_cache/ and/or the /scratch/ directory may need to be adjusted (brief intro).
