Hi wow devs,

wownero and wownero-gui build ok. but i got error when i run it.

~/git/MONERO/wownero-gui$ ./build/release/bin/wownero-wallet-gui

$ sudo apt qml-module-qtquick-controls2

Any suggest? Why there is no ISSUE tab on wownero-gui repo?

I googled about this issue, but still no answer there.

Did you try to install other qt plugins maybe?
