A repository contains chained changesets [1], linked together
in a parent/child relationship (a tree).
If you try to pull changesets from repo A to repo B
and repo B doesn't have the *root* changeset of the tree
of changesets found in A but missing in B, then Mercurial will abort
with that warning.
Simple example:
repo A: CA1 -> CA2 -> CA3
repo B: CB1 -> CB2 -> CB3 -> CB4
If you try to pull from A to B then root changeset CA1 would have
to be added to B, which is most likely an error, as these repos
are unrelated.
So if Mercurial would have to add a new root when transferring, it
aborts with "repository unrelated".
