Hey there, great images. I am having some issues building it locally.

Password: Password too short
The command '/bin/sh -c cat password.txt password.txt | vncpasswd && rm password.txt' returned a non-zero code: 1`
Tried setting up a longer password but didn't work.

I just ran this and it worked fine. If you've been adjusting the password, can you please try again with the original password.txt (to make sure there are no extra invisible characters in the password)? If this does work then there must be an issue with the password that you have chosen - try a 8-character alphanumeric password to be safe.

adding a newline after the password fixed the issue for me

@sgshawnblanchard Would you mind sending in a PR with the fix please (or just letting me know what the exact changes are)?
