Please excuse the late reply.

If you open Python and manually run:

  import urllib2
  urllib2.urlopen('https://wiki.fysik.dtu.dk/gpaw/_sources/setups/setups.txt')

does this cause the same error?  It is supposed to do exactly the same
thing, but without referring in any way to the installed GPAW, so
presumably the effect will be the same.

In that case it would be an issue between Python (urllib2), ssl, and
the DTU/CAMD web server - as far as I can tell.

If it yields the same error, can you find other https pages where urlopen works?

An alternative is always to install the setups manually.
