Hi,

Since 2020, I provided several examples of breakage with bug#39885 [1].
Here another one:

Well, several comments:

 1. Berlin or Bordeaux do not have it as substitutes,
 2. Diasarchive does not have it,
 3. Many others neither.

but the question in the first place is: why is Bioconductor failing?
Because they do ugly things!

Our history reads:

f431d5e299 Sun Dec 15 15:38:51 2019 +0100 guix: Upgrade to Bioconductor 3.10
12e2aa96dc Sun Dec 15 15:38:55 2019 +0100 gnu: r-biocneighbors: Update to 1.4.1.
aece78fe2f Sun Mar 1 23:38:12 2020 +0100 gnu: r-biocneighbors: Update to 1.4.2.
8e518d4802 Sat Jun 13 01:19:38 2020 +0200 guix: Update to Bioconductor 3.11.

which means that Bioconductor removes v1.4.1 from their URI scheme
(even, I do not know if the tarball is still available on their infra)
and despite the fact Bioconductor v3.10 had released v1.4.1, then it is
not stable.

At the cost of more bandwidth, we could switch from url-fetch to
git-fetch.  Or we also could examine why Disarchive is failing here.
