I installed sage 6.10 through
sudo apt-get install sagemath-upstream-binary-full
on my ubuntu machine.
When I start sage shell, I got
patching /usr/lib/sagemath/src/build/cythonized/sage/structure/list_clone.c
Traceback (most recent call last):
File "/usr/lib/sagemath/relocate-once.py", line 85, in <module>
p('src/build/cythonized/sage/structure/list_clone.c').substitute().save()
File "/usr/lib/sagemath/relocate-once.py", line 51, in save
with open(self.filename, 'wb') as f:
IOError: [Errno 13] Permission denied: '/usr/lib/sagemath/src/build/cythonized/sage/structure/list_clone.c'
Is this going to be a problem?
