[mythtv-users] Fix for broken lirc package in Ubuntu 20.04

[scram69]

Hi Stephen,

Yes, this is a new 20.04 install.
However, it appears the issue is deeper than the MythTV response.  It turns
out, as soon as I start Mythfrontend, the lircd daemon shuts down.
In other words, I can restart lircd.service, and the syslog shows that
everything starts up OK and /etc/lirc/lircd.conf.d/mceusb.lircd.conf is
read:
Nov 13 13:20:45 mediaserver lircd-0.10.1[4262]: Info: Using remote:

ready, using /var/run/lirc/lircd
Nov 13 13:20:45 mediaserver systemd[1]: Started Flexible IR remote
input/output application support.

However upon launching Mythfrontend, I see this in the log:
Nov 13 13:21:08 mediaserver lircd[4262]: lircd-0.10.1[4262]: Notice:

At this point only the arrow keys work, and irw shows only the keyboard
input from the arrow keys.

Any ideas why mythfrontend would trigger lircd to shut down?

Thanks-
Steve
