First thing first, please note that we are speaking about tag 1.4.1 and
not 1.20.0.  And this 1.4.1 is gone from “our” infra since… ?? That’s
one of the things I do not like with Guix: I never know what to expect
from the infra.  Anyway, I have my list of TODOs for improving the
annoyances (I and maybe others have :-)); stay tuned. ;-)

Considering the state of “our” infra and how Bioconductor manages the
tarballs, many tarballs are lost forever, sadly.  Although the content
is still around, I guess.

Thanks for diving into this.

Please note that Bioconductor 3.18 released BiocNeighbors v1.20.0 but
then updated to v1.20.1 still under Bioconductor 3.18 and Ricardo did
this update with 5673484cbc2ed74c61ae81d623646fa7829fbc32.  On a side
note, between the Bioconductor update and the update on our side, there
is a mismatch where the source of r-biocneighbors is unreachable.

Other said, post-update on our side,

As explained in [1], Bioconductor removes v1.20.0 from their URI scheme
and despite the fact Bioconductor v3.18 had released v1.20.0, arf!  And
I do not even know if the tarball of v1.20.0 is kept on Bioconductor
infra.  Hum?

Hence the discussion we had: switch from url-fetch to git-fetch.
However, after some investigations, it does not seem straightforward:
The main issue being the almost automatic current updater.  See for
details [2].

I did stuff past week about that.  I will report this week what I did.
