Note

• 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- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin
• You must have xdg-utils, wget, xz-utils 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 folder will remove 99% of installed files.
• You need GLIBC 2.18 or higher and libstdc++.so.6.0.21 (from gcc 5.4.0) or higher to run calibre
• If you get an error Could not load the Qt platform plugin xcb you are missing some needed X11-XCB libraries, such as libxcb-xinerama0, for details see here.
• You can change the folder calibre is installed into from the default (/opt) like this: sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin install_dir=/opt Change /opt above to whatever folder you want calibre automatically installed to.
• You can also do an 'isolated' install that only touches files inside the installation folder and does not need to be run as root, like this: wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sh /dev/stdin install_dir=~/calibre-bin isolated=y

Dependencies

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. In addition to those dependencies various build time requirements such as pkg-config, a C/C++ compiler, etc are needed.

calibre works on Windows 8 and 10.

Note

64bit calibre can be installed at the same time as 32bit calibre. The two calibre installs will use the same book library, plugins and settings.

If you are using Windows 7 or Vista, please use calibre 3.48, which works with all Windows 7/Vista machines, from here. Simply un-install calibre and install 3.48, doing so will not affect your books/settings.
