Upstream missing (uncompressed) Packages index, aptly mirror update fails

[oCCtet]

Steps to reproduce:

$ aptly mirror create trusty-main-ru http://ru.archive.ubuntu.com/ubuntu trusty main
...
Mirror [trusty-main-ru]: http://ru.archive.ubuntu.com/ubuntu/ trusty successfully added.
You can run 'aptly mirror update trusty-main-ru' to download repository contents.

$ aptly mirror update trusty-main-ru
...

ERROR: unable to update: HTTP code 404 while fetching http://ru.archive.ubuntu.com/ubuntu/dists/trusty/main/binary-arm64/Packages

The Release index lists the uncompressed Packages index, while that file really is missing from the upstream mirror. So the root cause may be a broken upstream mirror -- it was working with aptly just fine only a few days earlier. (This is *not* specific to Russian mirror, the root at archive.ubuntu.com is the same.)

Perhaps aptly could be satisfied if any one of the Packages indices (uncompressed, gzip- or bzip2 -compressed) is fetched successfully? They are after all redundant.

Hi!

This has been already reported, the problem is that Ubuntu Release file lists many architectures as being available: http://ru.archive.ubuntu.com/ubuntu/dists/trusty/Release (see Architectures: field), while actually only some architectures are present.

Workaround: specify architectures explicitly, e.g. in your case:

  aptly mirror edit -architectures=i386,amd64 trusty-main-ru

  aptly mirror update trusty-main-ru

The error message comes after aptly trying to download all possible versions of Packages file (compressed, then uncompressed), and it fails to download any of them.

Indeed the workaround works, thanks! I have always explicitly specified architectures, but now I forgot. (And I failed to read the error message carefully...)
