I had Sage 4.8 running fine on Ubuntu 11.10. I did a new installation of Ubuntu 12.04 in a new partition, downloaded Sage 5.0 64-bit, verified the MD5 sum and unpacked, and ran ./sage. After the paths were reset, I got a slew of messages about "code for hash <x> not found". I deleted the Sage directory in /home and redid the Sage install, with the same result. In hashlib.py where the code issues the message, there is the note "some may not work due to the OpenSSL version not supporting that algorithm." I do have the latest level of the openssl and python-openssl packages that are available on the Ubuntu repositories, and it appears that the code is trying all the standard ones, nothing exotic. Any ideas?
