Package: apt
Version: 2.1.11
Severity: normal
Since a few days I have been observing this bug during regular “apt
update” / “apt upgrade” cycles, without any configuration change on my
side; I am not completely sure if all this started after the last
upgrade to apt 2.1.11.
apt finds (testing, unstable, experimental) InRelease files, downloads
them from the mirror, checks the signatures, and then downloads
Diff-index files that it regularly ignores, be it for Packages, Sources,
or Contents. The result is always a complete new full download, without
ever considering pdiff files and patching.
After investigating a bit I tried using the following Debug options:
apt -o Debug::Hashes=true \
-o Debug::pkgAcquire::Diffs=true \
-o Debug::pkgAcquire=true \
-o Debug::Acquire::gpgv=true update
and this was the result:

This is only an excerpt, but the same happens for all other suites and
components: the error is always "FailReason: WeakHashSums".
I then tried other mirrors getting the same results, then I manually
downloaded some of the Index files from the mirror and verified their
SHA256 hash sums: they correspond to what is written in the InRelease
files. This makes me think that apt is responsible for the failure in
hash sums checking.
