Same.
Downloaded the tar to try and get an idea, and looks like it's copied the theme files to
/www/luci-static/material
/usr/lib/lua/luci/view/themes/material
but just not then switched to that theme. There's also an "itusnetworks" theme in those folders.
This page indicates that luci should have a settings page to allow us to select the new theme once installed, but maybe ITUS have disabled it. Anyone know how to change luci themes via the shell?
Guts of the theme makefile within the tar, might help:
THEME_NAME:=material
THEME_TITLE:=Material
...
define Package/luci-theme-$(THEME_NAME)/install
$(INSTALL_DIR) $(1)/etc/uci-defaults
echo "uci set luci.themes.$(THEME_TITLE)=/luci-static/$(THEME_NAME); uci commit luci" > $(1)/etc/uci-defaults/30-luci-theme-$(THEME_NAME)
$(INSTALL_DIR) $(1)/www/luci-static/$(THEME_NAME)
$(CP) -a ./files/htdocs/* $(1)/www/luci-static/$(THEME_NAME)/ 2>/dev/null || true
$(INSTALL_DIR) $(1)/usr/lib/lua/luci/view/themes/$(THEME_NAME)
$(CP) -a ./files/templates/* $(1)/usr/lib/lua/luci/view/themes/$(THEME_NAME)/ 2>/dev/null || true
