Get error downloading audio of Youtube video

[gh12345-dev]

I was trying to download the audio of a Youtube video using youtube-dl. I had used this command before and it worked fine when I was using Linux Mint Sylvia, but doesn't work after I upgraded to Tina. I not very technically savvy (I got the command line code from a search and it worked fine on Sylvia). Thanks very much for any help or directing me to somewhere else. George
