(mhh, I wonder why I missed the initial report…)Not familiar with Debian bug system, so perhaps I did not follow the proper procedure?

Another good point would be running apt with:
-o Debug::pkgAcquire::Worker=1 -o Debug::Acquire::http=1Will try this during the week, once the downloaded files get expired.And is "repeatedly" meant to refer to "reproducible all the time" or
"happens often, but no obvious pattern"?The pattern I was able to detect is that:- It always happen on files related to dep11 and icons, which are quite big.- Happens 50% of the time- Happens on debian 8 and debian 9 (will collect same set of logs on the newer template)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.Now that I realize the proxy is a suspect, I will clone the template and perform the same update with and without the proxy. That should provide some clues. Same goes for the "bare minimum" apt-config file.Thanks for the suggestions,///Pablo
