[tex-live] problems with tl2016 pretest

What do you mean with "overlap"?

The installer does the following:
for each package to be installed:
  download the file
  check size and checksum
  unpack into destination
done

Where the 'download the file' has several fall back:
- first try LWP, that is persistent connections
- if that fails, try wget (a few times)
- if that fails, too, give up

So I dont know what you mean with overlap.

I have to agree with Karl here. Unless the math.utah mirror really
rejects ftp (which Nelson said it doesn't), all this looks really
strange and - not by me - to me. I want to say, I am simply using the 
perl modules LWP, which *should* (and in 99.99999%) work correctly,
as far as I know. The warning message above are from LWP itself and
really look strange.

Some guess work from my side: 
Do you have a firewall (local or local network) that blocks ftp or
active ftp?
Do you need proxies for ftp?

All these things could influence the outcome ... hard to analyze from
here without physical access to the network.

All the best

Norbert
