10:44 <smoser> is there a fine manual that ii'm supposed to read for
10:44 <infinity> jbicha: Bah.  That's bound to be mythtv-specific.  Lemme look.

10:44 <ubottu> Launchpad bug 1728616 in apt (Ubuntu) "using 'devel' in sources.list causes apt-get update to fail" [Undecided,New]
10:44 <infinity> smoser: Yeah, don't use devel in sources.list.
10:44 <smoser> i'm guessing this is known to some extent. i can't be the only one that is using devel
10:45 <infinity> We should delete all references to it and call it a pointless and failed experiment, IMO. :P
10:46 <smoser> infinity: thats fine with me.
10:46 <smoser> you're welcome to comment in that bug.
10:46 <infinity> But it's been known not to work for a long time.
10:46 <smoser> i'm not sure how we got across the transition to artful
10:46 <smoser> on this system.

Title:
  using 'devel' in sources.list causes apt-get update to fail

Status in apt package in Ubuntu:
  Opinion

Bug description:
  Our /etc/apt/sources.list looks like this:
  $ cat /etc/apt/sources.list
  | deb http://archive.ubuntu.com//ubuntu devel main restricted universe multiverse
  | deb http://archive.ubuntu.com//ubuntu devel-updates main restricted universe multiverse
  | deb http://archive.ubuntu.com//ubuntu devel-security main restricted universe multiverse
  | deb http://archive.ubuntu.com//ubuntu devel-backports main restricted universe multiverse

  I noticed today that 'apt-get update' started failing.  Likely that
  started on Thursday or Friday when bionic opened.

  This seems less than desireable, but even if the failure is expected, what is
  the solution to "accept" this change?

  It does mention 'apt-secure(8)' but nothing there obviously points to
  the solution.
