  The calibre home page is at [https://calibre-ebook.com](http://calibre-ebook.com) As this is open source you can see what is included in the download. The source is on [Github](https://github.com/kovidgoyal/calibre)
  
  In general for all downloads never download from a place that lists downloads always look for the author's home page. Or you can trust places you know about by other means than a simple search.

  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`).
  
  I therefore use a small script named `update-calibre`. 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](http://calibre-ebook.com/download_linux).
  
  So whenever the calibre interface tells me there is a new version I run `update-calibre` and restart to have the latest version.
  
  ```
  #!/bin/bash
  
  # change this to your preferred install location,
  # **and** update the `sudo python` line!
  BASE=/opt
  
  # make sure the server stops
  killall calibre
  E=$BASE/calibre/calibre
  if [ -e $E ]; then
     V=$($E --version  | tr ')' ' ' | cut -d ' ' -f 3  )
     sudo mv "$E" "$E-$V"
  fi
  
  sudo python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urlli
  b.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.cali
  bre-ebook.com/linux_installer').read()); main(install_dir='/opt')"
  
  ```
  
  Make sure the last line in the script corresponds to the one specified on the linux install page.
  
  Killing the `calibre` process is necessary, as closing the interface keeps calibre running. 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.
