Basically, I disconnected the Wi-Fi :D right when the package was
downloading. On Windows, the line is `netsh wlan disconnect`... The
original problem occurs (more or less) when the connection is unstable
and the package download fails.

I tested it with and without the backup file (apologies for not
providing more details). I deleted the backup file to try to understand
what was happening; the important line is:

D:texlive-scripts remote revision 76658, texlive-scripts local revision 76648

In other words, `tlmgr` attempts to update from `76648` to `76658`, but
after the experiment, the following is obtained:

27-10-2025  19:57                 0 texlive-scripts.r76648.tar.lz4

Which indicates to me (from my perspective) that there is a problem
with the backup logic when creating one of size 0 (did it do so after
deleting the files?...or how does it fail?

Anyway, here's a reproduction of the problem under Linux (Fedora 43
update). These are my directories before the experiment:

To reproduce the problem, I first restored to the previous version (NOT
deleted the backup):

The plan now is to update to the current version and let the download
fail, using `nmcli radio wifi off`, and see what happens with the
directories and files. Let's test it:
