Sage installation
I use a "new" laptop, Lenovo Thinkpad T510 with Ubuntu 11.10. I have on it a not too good install of sage 4.7.2.(It means there were some error when it was installed, but it seems, it runs, but there are errors) I did'nt found any way install or upgrade Sage: 1. From source there is a problem with installing the python package (It is true for 4.6, 4.7.x, 4.8) 2. The upgrade says, "There are uncommitted changes in the Sage root repository". Please, I don't understand mercurial and i don't want learn it. 3. From binary of 4.8 the answer is "No module named _md5"
Do you have openssl (it's an ubuntu package) installed? Perhaps it will cure "No module named _md5" thing.
The binary must match the version, certainly. Just built it from source! It's easier than it sounds...
I use Sage from version 3.x. The problem begin at 4.7.x and with Ubuntu 11.x.
I installed the libssl0.9.8 package; the binary distribution runs. But what is the "ocal/lib/python2.6/site-packages/distribute-0.6.16-py2.6.egg/pkg_resources.py:2322: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal" message?
