Incorrect package checksums for trusty-updates since this morning

[gcc]

I am getting checksum mismatches on trusty-updates since this morning. It seems that the files were changed:

$ wget -O- -o /dev/null http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/binary-amd64/ | sed -e 's/<[^>]*>/ /g'
 Index of /ubuntu/dists/trusty-updates/main/binary-amd64
       Name Last modified Size
      Parent Directory &nbsp; -
      Packages.bz2 28-May-2015 10:23 513K
      Packages.gz 28-May-2015 10:23 650K
      Release 28-May-2015 10:23 104

These are the expected MD5 hashes:

$ wget -o /dev/null -O- http://archive.ubuntu.com/ubuntu/dists/trusty-updates/Release | egrep main/binary-amd64/Packages.'(gz|bz2)' | head -2
 2684076da64123b17dd4370f381444a1 665944 main/binary-amd64/Packages.gz
 db2bb58fc4545ae77d0ad0850d3d07d0 525354 main/binary-amd64/Packages.bz2

Packages.gz appears to be wrong:

$ wget -o /dev/null -O- http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/binary-amd64/Packages.gz | md5sum
407e592770cac05d3e27e7ae4425f0aa -

But Packages.bz2 is correct:

$ wget -o /dev/null -O- http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/binary-amd64/Packages.bz2 | md5sum
db2bb58fc4545ae77d0ad0850d3d07d0 -

Users may not be noticing because most of them are using bz2 compression, but MAAS fails on maas-import-pxe-files.

The difference appears to be in the Phased-Update-Percentage values:

@@ -74527,7 +74527,7 @@

 Origin: Ubuntu

+Phased-Update-Percentage: 30

with the Bz2 file having 30% versus Gz having 10%, so this looks like an incomplete file update/regeneration.
