Thanks, that got me out of a bind. I've done a little looking around and I can't find an explanation as to why this is necessary though. Is it a bug? Is it intended behaviour? If so, do you know why, and what the intended benefit is?

This is due to something to do with file and directory permission. If you do ls -al you will see in your directory that root user does not have execute capabilities. If you really need to run the dockerfile on the current directory, you will have to change the dockerfile permission using the following command.
chnod 777 ./dockerfile.
I hope that helps.

Thanks for the video, the problem is that we've used the home directory to build our stuff
you can go anywhere under your home directory to build your image, for example :
cd /home/user/Desktop
sudo docker build .

Sorry. A bit more detail about the gap, please.
