[mythtv-users] XMLTV out of date on Ubuntu 18.04

[Jim Abernathy]

In the Mythtv XMLTV wiki it mentions that xmltv package is out of date 
which it is (0.5.7) It mentions a fix of adding:

deb http://ftp.us.debian.org/debian sid main

to the /etc/apt/sources.list, etc.

However you can't do the install because of a missing key signature.

The bottom line is I can get xmltv installed and up to date, but it's a 
real pain using the old package, plus 2 different github installs to 
finally get there.

My point is, since v31 requires the use of XMLTV for ScheduleDirect EPG 
it needs to be easier.  I use tv_grab_zz_sdjson_sqlite and it's not even 
up to date on the xmltv github site.

Maybe it's a simple fix of the Mythtv XMLTV wiki instructions to tell 
the user how to get the xmltv from the right repository along with the key?
