It is been a long 10 hours without further updates...
hummm..
I had the same issue.
nothing seems done at the backend.
So I remove the update flag and maintenance flag.
Then wait for 2.0.4..
2.0.4 is out now.
And I went into the same problem again...

Did you check your apache and php logs? I just had the same issue and saw that it was a memory timeout for composer. Increased it to 4gb and it updated ok.
