LIRC on Xubuntu 20.04: control process dump core

Post by peter_b »

Running "apt install lirc" on Xubuntu 20.04.6, fails to install lirc package - and leaves apt in an unclean state:
Setting up lirc (0.10.1-6.1) ...
Job for lircd.service failed because a fatal signal was delivered causing the control process to dump core.
See "systemctl status lircd.service" and "journalctl -xe" for details.
invoke-rc.d: initscript lircd, action "start" failed.

[SOLUTION]
Make sure "focal-updates" as package source are enabled in /etc/apt/sources.list, like this:

Code: Select all

## Major bug fix updates produced after the final release of the
## distribution.
deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
# deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
Then revert the broken lirc package installation (apt remove --purge lirc) - and reinstall.
