(mhh, I wonder why I missed the initial report…)

Another good point would be running apt with:
-o Debug::pkgAcquire::Worker=1 -o Debug::Acquire::http=1
And is "repeatedly" meant to refer to "reproducible all the time" or
"happens often, but no obvious pattern"?
Interesting is the failure in copy ("E: Failed to fetch copy:") as that
is supposed to "just" move files around without (un)compression – and we
have passed the stage proxies could interfere as the download itself
verified (or not, maybe it IMS hits in some way and copy is supposed to
verify it – there are various ways such a not-modified state can be
reached and proxies are notoriously bad with it…).
btw: It is best to run apt with the least amount of config usually. The
mentioned config options are rather special case and especially the
"Acquire::BrokenProxy" one doesn't even exist… (I looked once, it seems
to have existed ~10 years ago for one year in no stable release and the
name was very bad for what it actually did…). Rule of thumb: If you
don't know what you are doing, use neither – unfortunately it seems the
people commonly answering questions on q&a-sites tend to be in the very
vocal "no idea, but I get points for posting stuff anyhow" group.
