This is overly broad, and will set the executable bit on many files that aren't executable. I used

chmod a+rx /opt/dropbox/dropbox-lnx*/*.so

It’s strange, I can’t build the image. It fails at
gpg: requesting key 5044912E from hkp server pgp.mit.edu

Aha, I got it working by installing ca-certificates before the first RUN command. But it’s in there too, so I’m not sure why it won’t work. Possibly the apt-get comes after the gpg key fetching.
