Please reconsider running this as root. I strongly recommend against it.
You should change the ownership to some standard user and perform the
installation that way. This is generally good advice, since you have no
reason to trust that scripts like this are bug-free (whether malicious or
not), and you don't want one of those mistakes to ruin your computer. It's
happened before (albeit not with amber to my knowledge).

Looks like the download timed out. Did you lose internet connection part
way through downloading the update? The file is downloaded in chunks of 4
KB, and if any of these take longer than the default timeout (10
seconds), then this error will occur.
If you know you just have a slow connection, then you can explicitly set
your timeout value using:
./update_amber --timeout 60 --upgrade
This will use a 60-second timeout for online queries. Since update_amber
did not make any attempt to upgrade from AmberTools 12 to AmberTools 13 (it
just rolled back some updates to prepare), you can simply try again.
Good luck,
Jason
