Comment 21 for bug 1605887

- Bugs against "ubuntu-mate" may be invalidated by the bug supervisor when they can be filed towards a specific package. (See after comment #11 for when that happened)
- Yakkety is EOL (end of life) and won't be possible to update that release anymore.

Please see bug 1721965 for Artful (17.10), as a fix is committed but not yet released.
