ONLY DO THAT IF YOU DO NOT HAVE PERSONAL WORKSHEETS FROM SAGE NOTEBOOK
STORED ON YOUR COMPUTER OR YOU WILL LOSE THEM !


Those are stored on that directory.

If you have such worksheets, do that instead:

To keep a backup of the worksheets:

    sudo cp -a /home/a/.sage/ /home/a/.sage.save

To change ownerchip of the directory:

    sudo chown -R ${USER}:${USER} /home/a/.sage/

Ciao,
Thierry
