Miktex wants to install xetex-def package in order to compile. It cannot be installed automatically from package depository because of server error (error response from server:404).
Package files can be downloaded from http://www.ctan.org/pkg/xetex-def. Though I haven't found any package documentation with installation instructions.
After downloaded from CTAN, there are just .def files. Where to put them?

MiKTeX Package Manager is synchronized with the last used 'Package Repository'.
Your error occurs when the last used one is a CTAN mirror, which is currently down.
To overcome this, choose a different mirror through the command 'Change Package Repository' from the 'Repository' menu, as shown in the following image:
After a MiKTeX update, it is also recommended to run the 'Synchronize' command from the same menu, otherwise you lose the synchronization between your installed MiKTeX distribution and the latest one available on CTAN.
Looking into http://mirrors.dotsrc.org/ctan/systems/win32/miktex/tm/packages/ I see there is savesym archived as savesym.tar.lzma, but according to your log file the (older) CAB version was requested. For the reason I can only guess, that this mirror was not up to date some days ago (it is now).
So some general hints:
You can check whether your selected mirror is (officially) up to date on MiKTeX Package Repositories.
On each update a file
mpm.iniis updated first. This can also be found in archivemiktex-zzdb1-2.9.tar.lzmaon each mirror. Forsavesymyou can among other entries read there:[savesym] Type=TarLzma
So, if you’d get this error message again, you could check, if there would be a inconsistency.
