Install Updates could not fetch the package cache information lists - NOSPLIT

[stevef]

The NOSPLIT problem is hard to pin down.  In your report it seems to be limited to just the tvheadend software which tends to rule out some of the reported causes and fixes and tends to suggest a problem with the remote end.

Did the start of your update problem coincide with any significant system changes ?
Was tvheadend installed on the system and working well for a significant time before the update problem started ?
Can you describe how your system connects to the internet ?
For example is it a virtual machine, or behind a firewall/proxy set up ?

Please post the log of the most recent failed update.
