bro, wget - O (alphabet O)… not number 0. I got the same error as well… but after checking it says unrecognized option… so the error is in the option. So I tried changing from the number 0 to alphabet O, and it worked.

Nice one! Thanks.
My HACS wasn’t even starting properly, so there was no option to try and update it, and it wasn’t displaying available updates for the associated integrations.
I ran the command line, re-started HA (I’m on a RPi) and everything fired up correctly.
