sometimes repositories are heavy and no send nothing.
but im sure , its worked.
upgrade-packages are dangerous ... you can break system.
only is good idea to find some libraries, games or other pacakes when not in system.
upgrade some packages can turn off some aplicactions.
im not use never "update-packages" ..only ..when some aplication say "need " , this library version.
