But according to [Obsolete] How to populate EPG data with zap2xml - #7 by wbeard52 I should be using zap2epg. So, using the info you gave me above, I’m guessing I should instead type:
cd ~
wget https://github.com/edit4ever/script.module.zap2epg/releases/download/v1.0.0/script.module.zap2epg-1.0.0.zip
unzip script.module.zap2epg-1.0.0.zip
sudo cp script.module.zap2epg/bin/tv_grab_zap2epg /usr/bin
sudo chmod 755 /usr/bin/tv_grab_zap2epg
