Download for linux

The latest release of calibre is 2.82.0. What's new.

Please do not use your distribution provided calibre package, as those are often buggy/outdated. Instead use the Binary install described below.

Binary install

calibre has a binary install that includes private versions of all its dependencies. It runs on 32-bit and 64-bit Intel compatible machines. To install or upgrade, simply copy paste the following command into a terminal and press Enter:

sudo -v && wget -nv -O- | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(; main()"

While you wait for the download to complete, please consider contributing to support the development of calibre.


  • If you get an error about an untrusted certificate, that means your computer does not have any root certificates installed and so cannot download the installer securely. If you still want to proceed, pass the --no-check-certificate option to wget, like this:
    sudo -v && wget --no-check-certificate -nv -O- | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(; main()"
  • You must have xdg-utils, wget and python ≥ 2.6 installed on your system before running the installer.
  • You can uninstall calibre by running sudo calibre-uninstall. Alternately, simply deleting the installation directory will remove 99% of installed files.
  • You need GLIBC 2.17 or higher and (from gcc 4.7.0) or higher to run calibre
  • You can change the directory calibre is installed into from the default (/opt) like this:
    sudo -v && wget -nv -O- | sudo python -c "import sys; main=lambda x:sys.stderr.write('Download failed\n'); exec(; main('/opt')"
    Change /opt above to whatever directory you want calibre automatically installed to.
  • You can also do an "isolated" install that only touches files inside the installation directory and does not need to be run as root, like this:
    wget -nv -O- | python -c "import sys; main=lambda x,y:sys.stderr.write('Download failed\n'); exec(; main('~/calibre-bin', True)"

Manual binary install or reverting to a previous version

If you wish to revert to an earlier calibre release or download a calibre upgrade manually, download the tarball of that release from here (choose the 32-bit or 64-bit version, as appropriate). Assuming you want calibre in /opt/calibre, run the following command, changing the path to calibre-tarball.txz below as appropriate:

    sudo mkdir -p /opt/calibre && sudo rm -rf /opt/calibre/* && sudo tar xvf /path/to/downloaded/calibre-tarball.txz -C /opt/calibre && sudo /opt/calibre/calibre_postinstall

Source install

WARNING: calibre is a highly complex piece of software with lots of very finicky dependencies. If you install from source, you are on your own. Please do not open bug reports or expect any form of support. You have been warned.

If you're still determined to install from source, read on:

  1. Make sure your system has python 2 installed.
  2. Install the various dependencies listed below
  3. Run the following commands in a terminal:
curl -L | tar xvJ 
cd calibre*
sudo python2 install


The up-to-date list of dependencies that the official calibre binaries are bundled with, can be seen in sources.json. While calibre might work with versions of dependencies other than those listed there, it is not tested/supported.
