My guess is that, when using sudo to run Sage, it created the
$HOME/.sage/temp directory which is only writable by root.
You can fix this with the chown ("change owner") command. From your home
directory, do
$ sudo chown -R florian:florian .sage
(Obviously, you have to be root to change the owner of a file from
root to someone else.) That will recursively change the owner of all the
files in the .sage directory to you. Then, don't ever run Sage using
sudo again!
