Re: Shared notebooks

[kcrisman]

I'm forwarding this to the sage-notebook group, where it may get more attention.  I'm sorry I don't know the answer to this; it does seem important.

I can say that the symlink probably isn't the problem, since I just created a different notebook in my GDrive folder, pointed sage toward it.  

So.... Can anybody find the problem here? Is sage maybe storing a global file that tells it what notebooks exist? Anybody?

Hi all,

I have several Mac each of them with its own instance of SAGE and I used to share my notebooks via a symlink to a directory on Dropbox : each .sage directory on each machine had sage_notebook.sagenb symlinked to a directory on my dropbox. It worked well under version 5.0. Now I get the error below. I hoped that it would be solved with further versions but not yet.  What did change in SAGE and what could I do now ?

I'm doing the same, and getting the same errors, but using Google Drive. 

I can say that the symlink probably isn't the problem, since I just created a different notebook in my GDrive folder, pointed sage toward it.  

So.... Can anybody find the problem here? Is sage maybe storing a global file that tells it what notebooks exist? Anybody? 

This has come up again a few times.

Is there anyone who knows exactly under what circumstances it appears that the DOT_SAGENB 

folder will be created (well, try and fail)?
