That's weird, i have the latest openwrt with LuCI, but i can't find this rosy theme in Software tab, i find material and bootstrap, but not this... You have the link to the .ipk?
It's in the snapshots, not in 18.06.4 (current).
Ooh, that's why, sorry, pretty new here... But thanks, so, if i want to install on 18.06.4, i will have to compile right?
I guess so.
Yes, here is the step for how to compile rosy-theme in 18.06 https://github.com/rosywrt/luci-theme-rosy
