I will downgrade to 16.04., the dist-upgrade to 17.10 was a
mistake, resulting in problems with startx and newer kernels so
I have to use 4.10.
In my experience dist-upgrade are long and messy :)
Usually I create a partition on disk; install a fresh (K)ubuntu
on that partition; move data / config from old partition to new;
delete (or backup) old partition.
I have both kubuntu 17.04 and 17.10 and dmd works fine.
