Trying to re-install python
I am trying to re-install the sage python dist. Using command "sudo sage -f python-2.7.2.p4". I keep getting the error message 'this does not look like a tar archive Exiting with failure status. Error: failed to extract /usr/lib/sage/spkg/standard/python-2.7.2.p4.spkg'. Does anyone know why? I also tried from the sage notebook with the command "install_package('python-2.7.2.p4')" with same result. Running Ubuntu 12.04 in VM VirtualBox. Thanks.
