This bug was fixed in the package lirc - 0.10.1-6.1ubuntu1.1
---------------
lirc (0.10.1-6.1ubuntu1.1) focal; urgency=medium
* debian/lirc.postinst:
- restore the postinst snippet ensuring that the configuration files
exists. It was removed 0.10.1-5.1 in favor of making those proper
conffiles but the changes were reverted in 0.10.1-5.2 in an incomplete
way letting the file without configuration installed which leads to
the service segfaulting and the install failing (lp: #1874130)

Hello,
I have tried to install lirc on a fresh Kubuntu 20.04 Release
Candidate installation on a AMD Athlon X2 system. The installation
failed, with a half installed lirc package. This is leaving apt-get /
apt in a state, that makes it impossible to install other packages or
updates anymore, as it first tries to finish the lirc installation.
This is leaving the system in a state, where further software changes
or the usage of lirc are not possible.
After using Google to find a solution for the problem, I found this bug
report about lirc on Debian bugs website:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932779
The suggested workaround is to creating the file lirc_options.conf and to
continue the failed installation (which worked on my system) via:
sudo cp /etc/lirc/lirc_options.conf.dist /etc/lirc/lirc_options.conf
sudo apt-get install lirc
This worked on my installation brought the system back into a state, where
further software installations or updates via apt-get / apt work again.
