You can automate future calibre installs by specifying the
installation directory in the install command itself, like
this:

sudo python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read()); main(install_dir='/opt')"

Change /opt above to whatever directory you want calibre to be
automatically installed to
