Comment 9 for bug 1611737

Thanks, I already on 18.04. After uninstalling ROS, do-release-upgrade -d
starts works properly. But there is an another problem in upgrade proccess.
I have zfs raid as data storage. And after rebuting new kernel was unable
to load. Problem solves by by buting in old kernel and export-uninstall zfs
and install-import in new kernel.
Thanks for help with ROS packages!
