I am trying to install Splash for Scrapy.

According to its installation documentation, first of all Docker has to be installed. This has been successfully done.

Then I launch the Docker Quickstart Terminal and I try to follow the second step and pull the image. This is when the issue arrives:

$ docker pull scrapinghub/splash

After pulling, extracting and downloading; I receive the following message:

failed to register layer: Untar re-exec error: exit status 1: output: write /usr/share/fonts/truetype/arphic-bsmi00lp/bsmi00lp.ttf: read-only file system

Attempts

If I follow the documentation from GitHub:

$ docker run -p 8050:8050 scrapinghub/splash

I get the same error:

docker: open /mnt/sda1/var/lib/docker/tmp/GetImageBlob849866419: read-only file system

I also found some other threads talking about similar issues, but I did not find any solution, or at least I did not understand it.

I am not familiar with Virtual Machines or Virtual Boxes, so maybe I am just doing a very simple mistake.

Any ideas to solve the problem?
