ubuntu-release-upgrade should disable -proposed to prevent situations
like this. Please include your the file /var/log/dist-upgrade/main.log
which should contain information about your upgrade from 14.04 to 16.04.
DistUpgradeController.py contains the following code:
653 # Disable proposed on upgrade to a development release.
654 if (not entry.disabled and self.options
655 and self.options.devel_release == True and
656 "%s-proposed" % self.fromDist in entry.dist):
657 logging.debug("upgrade to development release, disabling proposed")
658 entry.dist = "%s-proposed" % self.toDist
659 entry.comment += _("Not for humans during development stage of release %s") % self.toDist
660 entry.disabled = True
661 continue
So you'd also see the above comment in /etc/apt/sources.list.

Title:
UEFI secure boot fails after 14.04 to 16.04 upgrade
Status in shim package in Ubuntu:
New
Bug description:
I did a release upgrade from fully upgraded Trusty/14.04.x to Xenial/16.04 today (amd64). There was no indication of any problems during the upgrade. Only oddly asking to disable secure boot on the shim level again (already had done this on Trusty). Also I had the proposed pocket enabled in Trusty before doing the upgrade (update-manager).
After reboot I get a textual error message that "image verification has failed" and I am presented with a menu to select a different UEFI element (this is a Lenovo x230).
I can disable secure boot in the BIOS and am then able to boot.
Not sure this is related to the issue but from the system booted without secure boot I tried to run sbverify and it returns the same error for all EFI binaries I tried:
# sbverify shimx64.efi
warning: data remaining[1170360 vs 1289424]: gaps between PE/COFF sections?
PKCS7 verification failed
140313718134424:error:21075075:PKCS7 routines:PKCS7_verify:certificate verify error:pk7_smime.c:336:Verify error:unable to get local issuer certificate
Signature verification failed
If there is any other info that is needed, let me know. Or/and if
there are any steps to resolve the issue, let me know, too.
