Indeed, this was the thing to do. I've made a fresh install (via git clone) 
of sage 6.9rc3 and ./sage -n jupyter works !
Sorry for the noise...

Well, the tree/develop gives sage-develop in zip but in git clone it's 
sage.git, I am compiling it and will see if it's sage 6.9 maybe I used 
to make a mistake ?

But last time I did it I had sage6.8

By the way a question : Sage 6.9 rc2 can't be otbain with git clone ?
I could get only the tar download. Otherwise with git it have
version number sage 6.8, even on develop button.

huh?
see https://github.com/sagemath/sage/tree/develop

Re: [sage-release] Re: Sage 6.9.rc2 released

[Henri Girard]

I can't say now as I have 15.04. To get sage-6.9 rc2 I got the zip on 
the git sage-develop. I tried sage.git (version 6.8 apparently) before 
but I couldn't compiled it because an error. After compiling sage-develop

I did in the repertory
./bootstrap
./configure
make -j9
After about 2 hours I had a running sage-6.9rc2 and sage 
--notebook=ipython works, (but I can't get latex just a table with latex 
command)
sage -notebook work perfectly and I installed sm-install.sh which runs 
very good (even latex this way).
As I use texmacs I move it in /usr/share/sage with a link. By the way I 
always keep the sage-6.8 from ppa, but doesn't work always asking for ssl.
I haven't been able to remake it ./sage -f python2 or python or python3, 
never works ?

But before I was on 14.04 but never got it working either !

I noticed something which blocked me for a lot of time, maybe you know it ?
After using different sage versions, I faced a problem in .local numpy ?
Not knowing why and being blocked with all what I used I decided to 
delete .local ! And everything works again...

Re: [sage-release] Re: Sage 6.9.rc2 released

[kcrisman]

I have a question about the new "required" use of pretty_print in these 
rcs.  I created this interact in class today.

@interact
def _(a = 3, f = x^2):
f(x) = f
D = diff(f,x)
I = integrate(f,x)
pretty_print(html("The derivative of ${}$ at $a = {}$ is 
${}$".format(latex(f(x)),a, D(a
pretty_print(html("The indefinite integral of ${}$ is 
${}+C$".format(latex(f(x)),latex(I(x)

show(plot(f,(x,a-1,a+1))+plot(D(a)*(x-a)+f(a),(x,a-1,a+1),linestyle='--',color='green'),figsize=3)

This looks quite different without the pretty_print in Sage 6.8 (what we 
are currently using in the lab here at AIMS); namely, the lines directly 
follow one another, I guess  elements or something (view source doesn't 
seem to get what I want for interacts).  With the Sage 6.8 behavior for 
pretty_print, we get big huge spaces in between - not optimal at all for 
presentation.

I won't be able to get to a computer with rc2 for a bit; does the new 
pretty_print with html do the (better) behavior of just having separate 
html lines without huge spaces in between?  Otherwise you have to zoom out 
so much that it's barely worth using.  Or is there some other way to 
multiline?  Using \n seems to work okay but that is somewhat annoying 
compared to actually being able to, you know, write multiple lines...

Thanks for any feedback!

Hi,

On Ubuntu 14.04 64bits, the build was OK but when I try
./sage -n jupyter
I get

The IPython notebook requires ssl, even if you do not use
https. Install the openssl development packages in your system and
then rebuild Python (sage -f python2).

Now the openssl development packages (libssl-dev) are already installed on 
this computer (Jupyter notebook is launched successfully from sage 6.8). 
I've tried
./sage -pip install pyopenssl
./sage -f python2
Both were successful, but the problem remains: ./sage -n jupyter returns 
the same error message as above.

Eric.

Note that , particularly mysteriously 
The following package(s) may have failed to build (not necessarily
during this run of 'make all'):


That's not good either.  Also, just setting the env var to blank didn't

I can provide more details later if you would find them interesting.

Aagh, it's *still* trying to download it, even though the env var 
SAGE_INSTALL_CCACHE is now not even showing up in the list!  Also trying to 
download gcc 4.9.2 (remember, this is from the tarball).  I will reuntar

I view this as a blocker bug.  Internet should not be required for Sage to

some firewall but in the meantime let's get this fixed.

Interesting.  I was in the meantime able to upgrade my previous 
installation and sagenb seems to work fine.  Still interested in that 
ccache thing - I had to reduce the load on my machine somewhat but now 
should be able to run a fresh build of rc2 from tarball.

Aagh, it's *still* trying to download it, even though the env var

gcc should be contained in the source tarball. This is fallout from the

Hi,
I build sage 6.9.rc2 on ubuntu 15.04 and got it working but then latex 
was n't working in ipython notebook command ouput was between frame like 
a table.

By the way a question : Sage 6.9 rc2 can't be otbain with git clone ?
I could get only the tar download. Otherwise with git it have version 
number sage 6.8, even on develop button.

I did; it recompiled many things and took a while.
But the problem is still there: ./sage -n jupyter results in the same
error message.

same error message:

Re: [sage-release] Re: Sage 6.9.rc2 released

Right. You bug report actually shows 3 independent bugs:
* GCC shouldn't be downloaded in the first place
* The failed download of the mirror_list doesn't give an error message
* The blank line without failed packages

The first one is fixed at #19347.

The third one was fixed at #18731, but the fix got lost somehow(???) and 
is fixed again at #19349.

What about the blank line with no failed packages?  Clearly a package 
failed.  So somehow whatever mechanism causes the package to be listed (I 
used to know what that is, but in the new build system I don't) is not 
working if a package is not even downloaded.  But that is still a failure 
in that package - OR there should be some separate message saying that 
there is a connectivity problem.  Because the final message isn't the 
connectivity message, it's the message about Sage not building, and even

SyntaxError: unexpected EOF while parsing

isn't exactly something that screams "you have a bad proxy setting", which 
is what turned out to be the case for me.

By the way, all normal tests passed on the build from scratch once I got 
the proxy issue sorted out, which is nice.
