The underlying lirc is fine in 18.04.  That page, like many others,
has found problems with the 18.04 lirc install and has failed to
notice that if you manually configure lirc, it works.  The install
package for lirc on 18.04 is badly broke though - all the Python setup
code does not work due to missing modules, and there are various other
problems with the default setup.  But once you fix the packaging
problems by running my script:

http://www.jsw.gen.nz/mythtv/lirc-ubuntu-18.04-install.sh

everything works as expected.  So there is no need to install a back
level version that is not compiled against the current 18.04 headers
and consequently has its own dangers.
