Apologies ditto.

Not using synaptic, I don't know why that path was chosen. But
you'd need world-execute all the way down from /root itself.
When I install yt-dlp, being lazy I download the package from
packages.debian.org, choosing the most recent version, typically
trixie's. I store it under /home/debian/trixie (or whatever), and
# apt-get install full-path
I consider this safe, and ignore the warning that's issued. IIRC,
my warning starts with "N: Download is performed … ".
I do this because I'm too lazy to change my sources.list, and
that has the side-effect that I can't accidentally install any
non-stable packages by way of Depends/Recommends/Suggests.
In the past I have placed packages in /var/cache/apt/archives/,
but I'm not sure whether I used apt-get with a full path,
or dpkg -i; it was so long ago.

Well, I'll admit that I'm mystified as to what the 283682-byte file
called tmp_sh actually is, and how it was obtained.

What I've never resolved is under what circumstances does
# apt-get install full-path
copy full-path via /var/cache/apt/archives/partial/ into
/var/cache/apt/archives/, leaving the copy in the cache,
and install it from there; or just install it directly
from full-path without all the copying. But I suspect that:
. performing the copying step ⇒ no warning,
. installing directly ⇒ warning issued.
Cheers,
David.
