Fresh installation error on db_mongo

[fmocking]

Hi, I'm trying to install NewsBlur to ubuntu machine. I've tried two times, one in a fresh virtual machine. Both of them returning the following error(s)

Any suggestions?

The problem is solved by changing the permissions of the ./docker/volumes/db_mongo with

chmod 777 docker/volumes/db_mongo/

It would be great if we can solve it permanently
