stages	<reply> The Ubuntu Kernel gets updated in stages. If you have the updated kernel, but do not have the corresponding restricted modules, you may be leaving yourself with no X when you reboot. If you have compiled binary versions of your video driver, eg from the nVidia site, you will need to recompile them for the new kernel. This is normal, and not a bug.

winusb woeusb woe-usb	<reply> Ubuntu does not have a recommended tool for preparing bootable Windows installation USBs. If you need one, consider using Microsoft's media creation tool from a Windows computer (see ##windows for support). If this is not an option, there are third-party unsupported tools like WoeUSB ( https://github.com/slacka/WoeUSB , sudo snap install --edge woe-usb ) that might work.
