What's the deal with: !! Couldn't download 'oxygen-icons-4.4.92.tar.xz'. Aborting.
Note the ".xz" extension. Where the heck do I get that? Why using something like this in the first place? Why don't the tarballs I downloaded from my local KDE mirror work anymore? Why should I trust tarballs that are not distributed by upstream?
Please, please, don't do that. I'm sure whoever is responsible for this is just misinformed about something. Thank you :-)
