    failed to install sage 4.7.1 on ubuntu 11.10

    i downloaded sage from sagemath.org ( sage-4.7.1-linux-64bit-ubuntu_10.04.1_lts-x86_64-Linux ), unpacked it and tried to do the first run as root. this produced the following error message:

    Code:
    $ sudo ./sage/sage

    ImportError: No module named _md5
    any ideas how this could be fixed?

    I can report that an attempt to compile the source code

    sage-4.7.1-linux-64bit-ubuntu_10.04.1_lts-x86_64-Linux.tar.lzma

    on a new installation of the official release of ubuntu 11.10

    gives the same error


    ImportError: No module named _md5
    make: *** [doc-html] Error 1

    I had the same issue. After installation of the package libssl0.9.8 it compiled without error.

    Aye I had the same error and sure enough installing libssl0.9.8 fixed it.

    the compiled version of sage 4.8 runs (again, with libssl0.9.8 installed) on ubuntu 12.04 as well!

    Sage usually has an official release just for LTS Ubuntu. And 12.04 will be one. So hopefully in May 2012 we will have Sage working out the box on 12.04.
