Ubuntu 12.04: Ipython Permission Denied
I am trying to install Sage on Ubuntu 12.04. I am still learning Linux and am a total newbie when it comes to Sage.
I grabbed the tar off one of the mirror sites and extracted it with no problems. The issue is when I try to execute sage. It says " cp: cannot stat `/home/username/.sage/ipython': Permission Denied ". That is not where I extracted to, and as far as I know, that directory doesn't exist. Is this some hidden directory? Is some file pointing it somewhere no files/directory exists? Do I have to change permissions on something pertaining to Ipython? I'm not quite sure what the problem is exactly. Any help is appreciated.
First, which tar did you download, binaries or source? Second, what command exactly did you execute? If you unpack the binary tarball to /home/username/sage-5.2 then you'd want to execute: `cd /home/username/sage-5.2; ./sage`
It's possible that there is a directory /home/username/.sage with the wrong permissions; for example, if you accidentally created it as root, but are now trying to run as 'username', you won't be able to create the subdirectory 'ipython'. Ideally, /home/username/.sage should be readable and writeable by you, not just by root.
