Thanks! I'm testing in a container, where i'm dropped in as root, so I didn't even notice i'm appending as a regular user.
I'm gonna edit my post.

I made a boo boo typo, my bad. Correct commands: sudo apt-get install dirmngr sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 249AD24C sudo su -c "echo "deb http://ppa.launchpad.net/deluge-team/ppa/ubuntu trusty main" >> /etc/apt/sources.list.d/deluge.list" sudo apt...

Although you can disable uTP and with it, utp connections, it should not be an issue. Except perhaps, if you are using some weird package.
Where did you install deluge from? What version?
Since you disabled uTP, you are using ltConfig, right? What version of libtorrent is it reporting?

I'm not sure if this will help, but it looks like it (also default value is 1600 and that is where you start to see problems): Quote from libtorrent manual: active_tracker_limit is the max number of torrents to announce to their trackers. 1.
