Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
Err http://ppa.launchpad.net wheezy/main armhf Packages

W: Failed to fetch http://ppa.launchpad.net/jcfp/ppa/ubuntu/dists/wheezy/main/binary-armhf/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
BTW: why is "binary-armhf" tried? Is there a binary needed?

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
sabnzbdplus : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable
E: Unable to correct problems, you have held broken packages.
As you probably figured out, lsb_release on debian unsurprisingly returns a debian release name that doesn't exist on any ppa, causing the 404.
BTW: why is "binary-armhf" tried? Is there a binary needed?
Binary as in 'not the source package'. Listings of available goodies on repositories are organized by hardware-architecture, with arch-independent stuff such as sab simply added to the list for any and all archs. Hence that name.
sabnzbdplus : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable
This probably fails because the chosen ubuntu release is too new compared to wheezy, tripping over the multi-arch support (notice how it says 'python:any' rather than just 'python'). Precise is the closest match for wheezy, should do armhf too.
