You can reproduce them with the following command from a git checkout at
commit 9e6256ba0f32ab12d61c914a3fed879dac881762, which is the tip of the
'wip-binaries' branch, based on recent 'master':

Do you get the same results?

To match what 'core-updates-next' expects, it would be good to upload
the files above, along with digital signatures, to the following new
directory:

  https://alpha.gnu.org/gnu/guix/bootstrap/i686-linux/20190815/

Thank you.

The string "texinfo-perl-compat" does not occur in the current
'core-updates-next' branch on Savannah, which is at commit
82eaac49ac983f28768d6623d802f41cbd7f779b.

However, that file name _was_ present in an older version of
'core-updates-next', before it was deleted on Savannah at some time in
the past.  I know this because I checked out 'core-updates-next' from
another one of my computers, and found that it was actually at commit
89e7f90d0b40bc4f15f902cc3b82c3effa87dd02 from last November.  I ran "git
fetch" and "git reset --hard origin/core-updates-next" to fix it, but
maybe there's a better way.

How is this kind of issue normally dealt with?  Is there a git cache in
Cuirass that can be cleaned?

      Thanks,
        Mark
