I tried to install sage from source and also from PPA on Ubuntu 12.10. Both of them finish the installation without any problem, but when I run sage I get the following error:

k1@Think1:~$ sagemath

But if I run it as root then it works fine. I have installed it all without root permission though. I thought it might be a permission problem and gave all the permissions for the files to the user k1, but still the problems exists.

So, I gained the permission to '/home/k1/.sage' and now it runs, but there are new errors:

[SageTerminalApp] Could not set security dir permissions to private.

[SageTerminalApp] Could not set pid dir permissions to private.

and I can't open the notebook().

the output of "ls -l /home/k1/ | grep .sage" is empty.

The output of "ls -l /home/k1/.sage" is :

Your error seems to be related to permissions. Can you be more explicit on the procedure you used for installation ? Moreover, can you copy/paste the output of the commands "ls -l /home/k1/ | grep .sage" and "ls -l /home/k1/.sage" ?

First I downloaded the sage package from the website and unzipped it and ran the make command. it was installed and worked fine with root, but not under the user k1. Then I deleted it and added the ppa to the sources and installed it from there, same problem.

I've added the output of those commands at the end of the main post.

As you can see with the output of ls, some of the directory within .sage are owned by root, namely ipython-0.12, sage_notebook.sagenb and tmp. I don't know how such a thing could happen ! You can change the permissions with the command

sudo chown k1:k1 -R .sage

The command chown is for modifying users, k1:k1 means that you change the user and the group to k1 and -R is for recursive.

After that, it may work.

That worked just as you said. Thank you very much.
