Re: [sage-support] can't run sage in texmacs

2018-08-09 Thread Henri Girard

I think the problem is since sagemath 5.0 about two years ago, if you 
look to texmacs mail list, you will find the problem, Adrian tried to 
correct it but as now it doesn't work , send to you the mail

Ah!  It contains

{
  "NotebookApp": {
"password": "sha1:af540ed8f4"
  }
}

(where I have deleted most of the password).  I moved that file away and
now all is well.

I will leave it to others to work out how that got there, but it may be
worth remembering in case this happens to anyone else.  I have no idea why
that file gets created or what I did/didn't do for it to be there when no
sessions were running.

Thanks for the suggestions, and especially to Volker.

John

The token is generated before launching the browser, and conflicting ports 
aren't a problem (jupyter just picks an unused one). Check for pesky 
environment variables like JUPYTER_TOKEN and/or try

sage --notebook=jupyter --no-browser --debug

2018-08-09 Thread Dima Pasechnik

note the warning

The port  is already in use, trying another port.

And that it tries to get you started on port 8889 instead.
Perhaps this is somehow broken...

What do you have on ?

The is nothing in there except for a file 'migrated' containing
2016-09-02T15:23:38.838391
(with no newline).  I have never done anything to configure jupyter.

As I said, it worked always before I built 8.3.

Yes, that is what I have always seen before.

I installed the package Dima suggested but that does not affect this
issue.  It still behaves as it did yesterday.  Now the output is

If I simply run chromium-browser on this machine (which I am logging in to

which at least shows that some of the error messages I get when trying to
run Sage jupyter notebook are nothing to do with Sage.

2018-08-09 Thread Dima Pasechnik

Did you try

apt-get install packagekit-gtk3-module 


At least this should fix
Gtk-Message: Failed to load module "pk-gtk-module"

The token does get generated for me, are you sure you don't have any funny 
configuration files in ~/.jupyter

Unless you override it in the config, the generated url should have this 
form (including the access token):
