After update-manager cancelled with the message as described above,
what did the trick was the following simple steps:

0) Close down update-manager

1) Manually download the missing deb-files using wget

2) Make sure those deb-files are not corrupt in any way (though I am
not sure how to really do that).

If they are corrupt, I think update-manager will discover that in
later steps below, and try to download them again. And the whole
problem here was that downloading fails for some reason.

3) $ sudo cp manually_downloaded_debfiles/*.deb /var/cache/apt/archives/

(not sure if that is dangerous)

4) Make sure that no deb-files with the same name as those manually
downloaded exist within /var/cache/apt/archives/partial .

If such files exist there, they are likely to be corrupt
(half-downloaded or whatever). Update-manager will discover the files
under /var/cache/apt/archives/partial in later steps, and *remove* the
corresponding files in /var/cache/apt/archives/ that were copied in
step 3, and try to download them again.

What I did was (not sure if this is dangerous)

$ sudo rm /var/cache/apt/archives/partial/*.deb

5) Re-run update-manager. Everything works.


Many many thanks to Wulfmann, Derek and David for all the pointers I
have been given! I've learned a lot.
