I want to upgrade my calibre,an ebook management. From it's site all I need just do the following:
sudo python -c "import sys; py3 = sys.version_info > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read()); main()"
however, once I executed it's asking me:
Enter the installation directory for calibre [/opt]:
does anyone know the default installation location of calibre installed by USC?
