I can assure you that you will continue to receive these messages for
a while (unless you unsubscribe from the relevant mailing lists).
Our rationale is that in order to carry out currently known attacks on
MD5, you need to create a twin of documents, one evil and one
harmless. In Debian's case, we prepare the data we sign on our
trusted infrastructure. If someone can sneak in an evil twin due to a
breach, more direct means of attack are available.
In practice, the download links themselves are the larger problem
because users might use them without checking anything. Eventually,
they will go away, together with the MD5 hashes. Newer versions of
APT also use the SHA-256 checksums embedded in the Release and
