Now x11-packages repository will use original names for packages. For example, libgtk2 now will be provided as gtk2, libgtk3 will be available as gtk3, libsdl - as sdl. List of changed packages: libatk --> atk libglu --> glu libgtk2 --> gtk2 libgtk3 --> gtk3 libmesa --> mesa libsdl --> sdl libsdl2 --> sdl2 libsdl-net --> sdl-net riscvemu-sdl --> riscvemu xorg-xvfb --> xorg-server-xvfb List of dependent packages (should be rebuilt with new deps): dosbox, emacs-x, galculator, geany, libepoxy, mtpaint, qemu-system-x86_64, the-powder-toy, tigervnc, wireshark-gtk, xarchiver. Note: depending on which packages are installed, it may be necessary to upgrade with 'apt dist-upgrade'.
