This results in a temporarily confused user, who does not understand why the newly downloaded version number does not show up in the interface, even though the program was started. Killing the calibre process is necessary, as closing the interface keeps calibre running. Make sure the last line in the script corresponds to the one specified on the linux install page. Sudo python -c 'import sys p圓 = sys.version_info > 2 u = _import_('urlliī.request' if p圓 else 'urllib', fromlist=1) exec(u.urlopen('ī/linux_installer').read()) main(install_dir='/opt')' # change this to your preferred install location, You can edit books in both EPUB and AZW3 formats. You can read, edit, create and even convert your ebooks into different formats. Instead, organize your eBooks in a virtual library with Calibre. Feel free to toss out your physical books. You can read your ebooks on your Mac in a variety of formats. So whenever the calibre interface tells me there is a new version I run update-calibre and restart to have the latest version. Calibre is an exceptional program for e-books.

It kills the currently running Calibre, moves the previous version from /opt/calibre ( prefix is easily changed) to a backup (/opt/calibre- ) and then downloads and installs the latest version to/opt/calibre` using the script provided on the calibre site specifically for Linux installs. I therefore use a small script named update-calibre.

Newer versions of Calibre come out on a regular basis and I have not found a site from where I can automatically install the latest packages for my Linux system using the normal packaging download system ( apt-get).
