The server may just be down temporarily. You can disable the 'cheleb' listings for now by unticking them in the Other Sofware tab of Software Sources:

gksu software-properties-gtk
# After closing Software Sources, run:
sudo apt-get update
You can try to enable it later if it was just offline. The second command should update the repository list. If you still get an error there may be one of the ppa listing you missed.
