OctoXBPS is a Qt based GUI front end to the XBPS package manager, derived from OctoPkg. It consists of a lxqt-sudo clone called qt-sudo used to gain root privileges, a package browser application used to search, install, remove and update packages and a system tray icon notifier to notify the user about package changes. The project is compatible with Void Linux.
# xbps-install -S octoxbps

You'll also need "curl" and "sudo" packages installed and your user to be a member of the wheel group.
Enjoy!
