Howdy all,

After install of 10.04 64bit ubuntu (with your help), upon first invocations sage reports: ImportError. Here is the trace back:


import sage.all_cmdline

from sage.all import *

from sage.databases.all import *

from symbolic_data import SymbolicData

from xml.dom.minidom import parse

from xml.dom.xmlbuilder import DOMImplementationLS, DocumentLS

ImportError: cannot import name DOMImplementationLS. Error importing ipy_profile_sage - perhaps you should run %upgrade? WARNING: Loading of ipy_profile_sage failed.

<<well, yes,="" i="" followed="" the="" sage="" advise="" and="" ran="" %upgrade,="" and="" got="" the="" same="" results.="" and,="" if="" i="" disregard="" all="" the="" error="" messages="" and="" proceed="" to="" something="" like:<="" p="">

sage: 3+4

NameError: name 'Integer' is not defined. >> Suggestions??

Are you running "./sage" or "./sage -n"?

Well, I re-downloaded and re-installed, [ based on the sound Alice-in-Wonderland principle that anything I can do the same way three times ... must be true ] and waited patiently, and ... it now all seems to work!

So, unfortunately I cannot claim to have augmented the field of useful installation knowledge to any great extent. But, as they have told me in a previous life in Samoa: "thank you, all, for your patience".

If you can move your OS to another drive, you might want to check for bad blocks on your current one. "sudo badblocks -wst random /dev/sd_"

The above command is DESTRUCTIVE, so use with care....backup first.
