xenial myth and mate livefses fail to build due to libgles1-mesa

[Adam Conrad]

[ SRU Justification ]
The mesa update in -proposed removed libgles1-mesa, which should be fine, as everything in xenial depends on libgles2-mesa except for two packages, both of which were fixed in updates. However, because task-based installation pulls in tasks from the release pocket, myth and mate accidentally attempt to install libgles1-mesa during the livefs build, and it's no longer installable.

[ Proposed Fix ]
Add libgles1-mesa to the task filter to remove it from the list of packages to install.

[ Regression Potential ]
Zip.

[ Test Case ]
See if mate and myth livefses build in proposed with this change. Make sure manifests look sane. Profit.

Hello Adam, or anyone else affected,

Accepted livecd-rootfs into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/livecd-rootfs/2.408.14 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Confirmed this fixed the myth and mate builds and didn't regress others.

The verification of the Stable Release Update for livecd-rootfs has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

This bug was fixed in the package livecd-rootfs - 2.408.14

---------------
livecd-rootfs (2.408.14) xenial; urgency=medium

  * live-build/auto/config: Filter libgles1-mesa out of tasks, as it is not a
    dependency of anything in updates anymore, fixing mate/myth (LP: #1704013)
