[Jackaudio] Zrythm and JACK

I'm using Trisquel 9 (Ubuntu 18.04 based) I'm trying to get JACK to function with Zrythm. I posted my issue here (https://redmine.zrythm.org/issues/1655) on the Zrythm bug tracker and was told that my issue is with JACK. In a nutshell, how do I solve this issue: ** Message: 23:24:21.436: Setting up JACK... no message buffer overruns no message buffer overruns no message buffer overruns unknown option character l connect(2) call to jackdmp 1.9.12/jack-1000/default/jack_0 failed (err=No such file or directory) attempt to connect to server failed
