Hi,   Same problem with same error message "...404  Not Found"   However I can share a tested workaround for Linux: 1 - Dowload the file here http://www.flirc.tv/downloads_linux/ 2 - Extract the zip 3 - Open a Terminal 4 - Go into the folder (ie: cd Downloads/Flirc-v1.2.2-x64) 5 - Enter: sudo ./Flirc 6 - Enter you root password   You can use the utility as well sudo ./flirc_util then choose an action then ie: sudo ./flirc_util version   Hope this will help
