Run Installer, tap 'Sources', tap 'Edit', tap 'Add', enter an address, tap 'OK' to refresh. (This will take increasingly longer, for each source added.)
Type each source as listed, they are Case Sensitive.
Another option, would be to add Shai's source, and then proceed to delete [tap 'Edit', tap the red circle alongside an unwanted source, and tap 'delete'] the undesirables.
i.e. foreign languages, HP calculator templates, the porn [Code Genocide] source....
Note: If a source repeatedly (...days) appears under the 'Untitled' header toward the bottom of the scrollable source list, consider deleting it, as the server is offline.
