Ubuntu 14.04 image contains a lot of unneeded packages
The Ubuntu 14.04 x32 image doesn't seem to be cloud optimized. There's a lot of extra cruft that shouldn't be there (possibly because of the GUI version of wireshark)
The following commands help to clean up the image.
apt-get --purge remove font* libx11* x11-* landscape-common w3m ntfs-3g ppp libxcl*
apt-get --purge autoremove
I hope DigitalOcean will come with better default images that don't contain all that cruft.
