Calibre

Manage, convert and read your ebooks with Calibre. Organise your library, edit book metadata and covers, convert between popular ebook formats, and read books with the built-in viewer.

Community-maintained snap

This snap packages the official Calibre Linux binaries, but the snap itself is maintained independently and is not endorsed or supported by the Calibre developers.

For installation problems, permissions, device access, or other issues with this snap, please report them to the snap maintainer:

https://github.com/popey/calibre-snap/issues

Please report issues with this package there first, rather than to the upstream Calibre project. The maintainer can help determine whether a problem is specific to the snap.

Connecting ebook readers and external storage

USB device access and access to mounted removable storage are optional permissions. They are not connected automatically.

To allow Calibre to detect and communicate with USB ebook readers:

 sudo snap connect calibre:raw-usb

To allow access to mounted readers, USB drives and other removable storage under /media, /run/media and /mnt:

 sudo snap connect calibre:removable-media

For a USB reader that appears as a removable drive, you may need both connections. Mount the device using your desktop's file manager, then restart Calibre. These permissions enable access; compatibility with every reader and MTP device has not yet been verified.

Without these connections, you can still manage and read a library stored in an ordinary, non-hidden folder in your home directory.

Using an existing library

Back up your existing Calibre library before switching installations. For an initial migration, use a copy of the complete library folder and select it in Calibre. Do not open the same library in the snap and another Calibre installation at the same time.
