2012-05-20 18:40:17 +0200 | asked a question | "code for hash md5 was not found" after fresh Sage 5.0 install on fresh Ubuntu 12.04 install 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". (The first message was about md5, but as you can see below, there were many others that failed.) I deleted the Sage directory in /home and redid the Sage download and 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? (more) |

2010-11-26 21:13:40 +0200 | commented answer | UnpicklingError when trying to run notebook() Thanks for posting the details of the paths and specific pickle files. Since I'm just trying Sage out, I didn't have to recover information, but I'll remember that this procedure is here. I don't know all the factors that can affect Sage's paths, but I actually found the snapshots, presumably the .bz2 files, under .../.sage/sage_notebook.sagenb/home/<user>/<worksheet id="">/snapshots. |
2010-11-26 20:55:48 +0200 | commented answer | UnpicklingError when trying to run notebook() Yes, renaming the folder took care of the problem. And realizing that there was such a folder was a big step forward. I see nothing in the Installation Guide that states explicitly that the Sage installation creates it. Now that I know it's there, I understand the statement in the Installation Guide about the DOT_SAGE environment variable. Thank you! |
2010-11-21 11:07:22 +0200 | commented question | UnpicklingError when trying to run notebook() Any ideas? I get this error consistently when I do a complete reinstall of Sage. Since others don't get it, and since I didn't get it the very first time I installed a prior level of Sage, I assume there's something about my environment that causes this. But I thought I read that Sage comes with everything it uses, so I have no idea what in my environment could cause the problem. |

2010-11-05 21:15:58 +0200 | asked a question | UnpicklingError when trying to run notebook() When I first downloaded and installed Sage (several versions ago) to try it out on Ubuntu, everything worked without error. I didn't do much with it, time passed, and when I came back to Sage, I saw 4.6 was there. I completely erased the folder that Sage was in, downloaded and untarred 4.6, and ran Sage. That's fine--commands input in the terminal work fine. But when I try to run notebook(), I get
I know how to spell Python, but not much more. Any idea what got messed up and suggestions on how to fix it? |
