uninstalled again

re-installed from Software Center

ran .... crashed .... finally got an error message with text content....

fldigi-dbg: Depends: fldigi (= 3.23.01-1~kamal~trusty) but 4.0.1-1~kamal~trusty is to be installed

If you remove the PPA and install the version from the Ubuntu repository is it OK?

opened "ubuntu software center" on desktop
removed FLDIGI and assoc programs
installed from "software center"
same version installed, same result .... crashes after about 30 seconds

do i need to remove command lines referring to PPA somehow?
do i need to install from a different source than the software center??
how do i get V 3.23.10 to install?? ... various web pages say it is stable

Let's try something. What is the output of:

grep fldigi /etc/apt/sources.list.d/*
