I just successfully installed OpenWrt on my new shiny GL-B1300, working so far quite well. I wanted to install a new theme I have added sources to opkg but I got error:
I have no idea what you're talking about (I'm still lost at why you're trying to put the [mirror of the] code repository into the router's package updater)...so it's really difficult to answer you...cause it sounds like you're asking me if I prefer a working vs. erroneous/non-working method.
Well, since you've been shown how to install officially packaged themes in OpenWrt...and you're not being clear on what you're doing (nor why you're doing it - or if you tried installing after being shown). I hope all works out for you...or you decide to elaborate more for the thread.
