[yocto] Package woes

[Gary Thomas]

This morning, I had built an image successfully using a slightly older
Poky/Yocto master (af9ed97e30ac1a3a2b4e1062f2f8aee255d05972).
Then I updated to master (90b98764555945a186562ca8d501a9585ce2b23f)

Now, when I try to build an image (any 'rootfs' image), I
get a ton of errors like these:
|  * opkg_install_pkg: Package python-modules md5sum mismatch. Either the opkg or the package index are corrupt. Try 'opkg update'.
|  * opkg_install_cmd: Cannot install package python-modules.
|  * opkg_install_pkg: Package libffi6 md5sum mismatch. Either the opkg or the package index are corrupt. Try 'opkg update'.
|  * opkg_install_cmd: Cannot install package gst-plugins-base-app.
|  * opkg_install_pkg: Package libx11-6 md5sum mismatch. Either the opkg or the package index are corrupt. Try 'opkg update'.
|  * opkg_install_cmd: Cannot install package gst-plugins-base-xvimagesink.

There are also a lot of messages like these:
| Found /home/local/imx6_poky/tmp/deploy/ipk/armv7a-vfp-neon/locale-base-sw-ke_2.17-r0_armv7a-vfp-neon.ipk in Packages, but mtime differs - re-reading
| Found /home/local/imx6_poky/tmp/deploy/ipk/armv7a-vfp-neon/locale-base-sw-tz_2.17-r0_armv7a-vfp-neon.ipk in Packages, but mtime differs - re-reading
| Found /home/local/imx6_poky/tmp/deploy/ipk/armv7a-vfp-neon/locale-base-szl-pl_2.17-r0_armv7a-vfp-neon.ipk in Packages, but mtime differs - re-reading

I don't understand this one at all because I tried rebuilding
virtual/libc-locale and I still get them.

Any ideas what's happening?  Sadly, I seem to be totally stuck
with this problem :-(
