Trouble with sage installation on Ubuntu 11.04
Alex Lara
Sage failed to install in ubuntu 11.04. I get the following error:
ImportError: No module named crypt
Error importing ipy_profile_sage - perhaps you should run %upgrade?
WARNING: Loading of ipy_profile_sage failed.
Any idea of how to fix this?
Thanks in advance:
Alex Lara.

A random shot in the dark is that you could try:
(1) installing the libssl-devel Ubuntu package with "sudo apt-get
install libssl-devel".
(2) rebuild the Python spkg in Sage:
cd SAGE_ROOT
./sage -f python
I have *not* tested this; it's just the first thing I would try, since
the error "no module named crypt" is a symptom of not having the crypt
module compiled into Python, which might happen if the libssl-devel
Ubuntu package isn't installed when you build Sage.

P.S. For a short while we used to include openssl with Sage, which
avoided such problems, but it turned out at the time that the openssl
license is GPL-incompatible, so it's somewhat unclear that we can
legally include it in Sage.

It's libssl-dev on Ubuntu (remove the "el" at the end).
But I can build sage/python without that package though.

It needs a one line patch on Ubuntu. Try instead (take note this is a work in
progress):
cd SAGE_ROOT/spkg/standard
wget http://users.aims.ac.za/~jan/python-2.6.4.p10.spkg
sage -f python-2.6.4.p10.spkg
( Note that only works after you did 'cd SAGE_ROOT; make', and it failed
to build the crypt module in the python spkg, but the other packages
are built.
Regards,
Jan

but sage -f python-2.6.4.p10.spkg did work (I think).
I ran make test. The following test failed:
sage -t -force_lib "devel/sage/sage/rings/number_field/
number_field.py"
Do you think my build is ok now?

In a word, No. What version of Sage are you trying to build?
Can you show us the output of the test log file (test.log, ptest.log,
ptestlong.log or whatever it is in your case). We need to see the bit where the
test fails - not the complete log.
If you have not run the long tests, I suggest you run them too.
$ make testlong
(run each test serially)
or
$ make ptestlong
(if you have a multi-core and/or multi-processor machine, which will run tests
in parallel to reduce the time needed to run them).
I have a faint recollection of "number_field.py" might have failed on one of the
recent alpha releases, but has been fixed. Depending on what you are using, you
might have hit a problem that's been solved. But I could be mistaken about this
anyway - I lose track of the test failures, which are quite common in the early
alpha releases.

I will run the long test and as soon as it finishes I will post the
output.

If your sage starts without an error about failing to import crypt, then
your build is OK as regards the python on Ubuntu 11.04 issue.
The fix is in sage 4.7 due out very soon.
Currently sage 4.6.2 finishes building python on Ubuntu 11.04 without
exiting, but fails to build the crypt module. You can even use much
of sage, but not the notebook, and with the 'import crypt failed' error
whenever you start sage. The new python spkg fixes the issue,
and will exit on any platform if the crypt module fails to build.
(make testlong doesn't show this error; it is a python build issue)
Anyone who built sage 4.6.2 on Ubuntu 11.04 can in the meantime (until sage 4.7),
after having built sage by running make, fix their installation with
sage -f http://users.aims.ac.za/~jan/python-2.6.4.p10.spkg

I was wondering. Since Mint is built on top of Ubuntu 11.04, is the fix in sage 4.7 hard coded to recognize Ubuntu 11.04? Could the same fix be expanded so that compiling would succeed on Mint as well?

Please type this in a terminal:
cat /etc/issue > mint-issue.txt
And post the file mint-issue.txt back as an attachment.
(To get the tabs and spaces just right a text attachment
is better.)

You won't see anything, but you will create the file mint-issue.txt in your
home folder. Please post that.

This is now http://trac.sagemath.org/sage_trac/ticket/11447
Bill, please replace SAGE_ROOT/spkg/standard/python-2.6.4.p10.spkg
with http://users.aims.ac.za/~jan/python-2.6.4.p11.spkg, and then
run make again.
