[mythtv-users] lircd unreliable after Ubuntu upgrade 16.04 > 18.04

[Fred Hamilton]

If I may hijack this thread, I'm in the same/similar situation: just
upgraded 16.04->18.04 and no LIRC.  I tried running your script but I get
this error:
bash: ./lirc-ubuntu-18.04-install.sh: /bin/bash^M: bad interpreter: No such
file or directory

I'm sure it's something simple but I'm not that knowledgeable about
scripting.
