Hi- I couldn't install MonetDB on Ubuntu 16.04.1 LTS (Xenial Xerus) hosted on EC2 yesterday. I kept getting the error below. It looks like the repository does not have a "source" folder. However, I noticed that the "Trusty" version had a "source" folder, and so I tried installing the Trusty version on my Xenial box, and it installed successfully.
So far, I haven't encountered any problems, but was there anything I did wrong in the installation process? Will I encounter problems down the road with the Trusty version installed on a Xenial box?
