Well you at least have one problem - the community repo no longer exists.
This probably means you have also ignored pacnews in general (one of which would be pacman.conf.pacnew).
Recent explanation:
Another problem is this - your list consists of a single mirror … and it is woefully out of date.
For 2015:36 hours:minutes … thats 84 days since it was synced with manjaro.
So … I suggest you rebuild your mirror pool … in this example I will target UK again … but you could add a few more countries as well …
sudo pacman-mirrors -c United_Kingdom
Then update again…
sudo pacman -Syu
(and remember you still need to handle your pacnews)
