higlass file not found in /tmp error

[pmanninghall]

Hello,
I am running ubuntu on a virtual machine situated in my windows comp.

I have installed Higlass-manage and docker. I can get the local blank higlass window using higlass-manage start and navigating to the local host on firefox.

However, when i try to add data using "ingest" or "view" I get this message. Note that when i navigate to /tmp "sample.mcool" is in the directory. The same sort of message also happens when I tried to load other data.

$ higlass-manage ingest /tmp/sample.mcool

state True
Inferred filetype: cooler
Inferred datatype: matrix
state True
state True
