I found where sage was actually trying to download the file, and copied
that code to write a little test, which looks like
import sys
try:
# Python 3
import urllib.request as urllib
except ImportError:
import urllib
# Change the URLopener to raise an exception on HTTP errors
def http_error_default(url, fp, errcode, errmsg, headers):
fp.close()
raise IOError(errcode, errmsg, url)
opener = urllib.FancyURLopener()
opener.http_error_default = http_error_default
# This reporthook is used below to print ...'s as the file downloads.
global cur
cur = 0
def reporthook(block, size, total):
global cur
n = 60*block*size
# n ranges from 0 to 60*total, so we'll print at most 60 dots
if n >= cur + total:
sys.stderr.write('.')
sys.stderr.flush()
cur += total
sys.stderr.write('[')
sys.stderr.flush()
filename, info = opener.retrieve('http://www.sagemath.org/index.html',
'/dev/stdout', reporthook)
sys.stderr.write(']\n')
and I get funny results.

works as expected. However,
jb12407@lmfdb3:~/test$ python urlopen.py > output
[Traceback (most recent call last):
File "urlopen.py", line 30, in <module>
filename, info = opener.retrieve('http://www.sagemath.org/index.html',
'/dev/stdout', reporthook)
File "/usr/lib64/python2.6/urllib.py", line 243, in retrieve
tfp = open(filename, 'wb')
IOError: [Errno 20] Not a directory: '/dev/stdout'
gives the error.
I don't know why. However, having just spent a bit of time fighting with
selinux while setting up apache stuff, I've decided that this must also be
some sort of strange selinux issue. Meanwhile, I can still install packages
by downloading them manually and putting them in the right place so that
sage doesn't download them.
