In fact we must obtain (sagemanifolds and I... maybe more...(I guess but i don't want to speak in name of Eric) the following : sage --notebook=ipython so we have access to sage kernel. With the following link you sent to me it works. Apparently ssl is inside or at least it doesn't ask for ! I too installed all the libs you mentioned. But no way to get the deb working (pity but not dramatic), I have to install it by hand sudo mv sage /usr/share/sage and sudo ln -s /usr/share/sage/sage /usr/bin/sage (before delete sage in bin sudo rm /usr/bin/sage), but that's not ubuntu original installation : /usr/lib/sagemath (but it's helping me when something get wrong like at the moment !), so I have two sage installed in different location and when there is a problem I connect to the working version. Anticipating a little wily seems to have problems with dir path python but I might be working properly when ready. Anyway thanks for your great job. For me it's not too annoying and I don't want to give you more work than necessary, it's a only a whish that maybe others can have. I am not qualified enaugh to tell you what's the problem with ssl (In my opinion it's more a problem of right or directory than ssl as I have put all lib ?)
Kind regards
Henri

    I just test it, ssl is always lacking
    But I am not sure this is the reason because libssl-dev is installed.
    Why not put in deb the sage-6.8 LTS, I installed it and it works

    Before I could compile sage but now I got errors that's why I like
    your deb and it's automatically updated.


I think due to other problems on many platforms the ssl is disabled by default in the Sage binaries. Other sage developers are more qualified to discuss that and answer that.

What is the "sage 6.8 LTS"? Do you mean include something other than http://sagemath.mirror.ac.za/linux/64bit/Ubuntu_14.04_LTS_sage-6.8-x86_64-Linux.tar.lrz in the PPA? Or do you mean depend on libssl-dev and include a rebuilt sage with pyopenssl in the deb? I coudl then be introducing errors/bugs to the downstream users if I include a rebuilt python with ssl. I want to confirm that it is possible though, with one or two lines, to add SSL capability.

Our (AIMS) main use case, by the way, is standalone laptop installs, that can work offline, so we use a per-user installation, not a multi-user server, so the https is irrelevant for us. I'd like to stay close to the upstream with the PPA. We do however have students ssh from a laptop into their own account on a campus desktop to use a notebook on a more powerful machine or just to access their worksheets conveniently from their rooms.

Right now we cannot on the -full package do either of

sage -i pyopenssl
or
sage -pip install pyopenssl

even though we did

sudo apt-get install python-dev libffi-dev libssl-dev libxml2-dev libxslt1-dev

Our

sage -f python was succcesful though.

What exactly are the commands and output of what you are trying to do?

Regards,
Jan
