> Thanks, Jason!
This is kcrisman :)
> I did as you said and the result was as predicted: the patch failed to
apply, but maybe for the wrong reasons again. Does the following error
message help?
Yes, because you didn't follow my instructions exactly ;-) though those
were on the sage-notebook list, not this ticket.
* Log in to a command line Sage.
* type '''exactly''' the following:
{{{
hg_sagenb.import_patch("http://trac.sagemath.org/sage_trac/raw-
attachment/ticket/8776/trac_8776-sagenb-undo.2.patch")
}}}
and see what happens.
Note the "hg_sagenb" instead of "hg_sage". We moved a lot of stuff
outside of the devel/sage/ directory into the devel/sagenb directory a
while ago, so this is necessary. Hopefully this will at least give a more
informative message. Thanks for trying it out - you're on your way to
becoming a Sage developer!
