I received this message:
Some requested packages cannot be installed: guile-2.0.9-2.mga4.x86_64 (due to conflicts with guile1.8-1.8.8-16.mga4.x86_64)
I aborted the upgrade, and await whatever advice might be forthcoming.
History/background info:
This computer is an HP Pavilion P7-1234 desktop, originally sold with MS Windows Home Premium x64, currently dual-booting with the latest update of Mageia 3.
Currently using the F3 Safe Mode fall-back basic Gnome GUI, because the current Mageia 3 version (possibly the fglrx driver) seems to have a minor incompatibility with the CPU-integrated AMD Radeon HD 6530D graphics display adapter. (Response to mouse-clicks was delayed for up to a minute and a half). Using Safe Mode provides full function.
