Jarno Suni, That possible cause seems irrelevant to Unattended-Upgrades. Any package installed by any front-end to apt will be upgraded. U-U doesn't know what packages are installed, nor care. U-U simply tells aptdaemon to upgrade packages from the repositories authorized by the user. U-U does not duplicate nor replace Software Updater, and both can safely be used.
Try running 'apt autoremove' (16.04) or 'apt-get autoremove' (12.04/14.04). If those kernels are not removed, then your problem is the apt-marking, not U-U. There are several ways to prevent automatically marking kernel packages as 'auto' - the most common is by installing kernel header packages. If those kernels are removed, then check the U-U logs in /var/log to ensure that U-U is really operating. A bug report is an awful place to try to troubleshoot in this way.

While you and I might know that we need to watch partition space, many of the people we have installing think that a windows disk is a disk and not a partition, education is probably the key - but in the meantime support venues keep needing to deal with the fact the partition is too small and/or old kernels are not purged as new ones install.
