Sounds like you have a partially installed Debian Buster. This is what can happen when you change your sources, but you don't do a full-upgrade. Generally it probably isn't good to run this way.

Now is a good time to upgrade to Buster at least! Buster is expected to release next week, and for the most part is ready for use, unless you have certain hardware that you want to keep on Stretch.

First, I would back up your data.

Next, I would change your sources to point to buster (not testing), and:

$ sudo apt update
$ sudo apt full-upgrade

and fully upgrade your system to Buster.
