Got some ePub and/or MOBI books in your PC? Debian / Ubuntu has recently includes a package in their repository for generating thumbnails for these files.
As you may know, Linux Mint 21 was released recently with a thumbnail generators for AppImage, ePub, MP3 and RAW files. Debian/Ubuntu now has similar tool called gnome-epub-thumbnailer
, though it’s only for ePub and MOBI books.
With the package installed, the default file manager will no longer display the universal “e” image with green background for all ePub files. Instead, it shows thumbnail book covers.
Don’t know if Ubuntu 22.10 will come with it out-of-the-box, since it’s not released yet. But, user may manually install the package by running the apt
command below in terminal.
Open terminal (Ctrl+Alt+T) and run command to install gnome-epub-thumbnailer
in Ubuntu 22.10 or Debian Unstable:
sudo apt update && sudo apt install gnome-epub-thumbnailer
NOTE: the package is only for the default GNOME Desktop! Install the Foliate eBook reader from system repository will also install it as recommend dependency package.
Enable EPub / MOBI Thumbnails in Ubuntu 22.04 | 20.04
The package is not available in the current LTS releases. Ubuntu 22.04 user can however download the .deb package directly from the build page:
Click the little triangle for Ubuntu 22.10 (Kinetic Kudu) build to expand, and select download the amd64.deb
for modern PC/laptop, arm64/armhf
for ARM, or other format depends on your devices.
Finally, double click to open the .deb
package via “Software Install” (Ubuntu Software) and install it.
For Ubuntu 20.04 user, I’ve upload the package into this unofficial PPA for 64-bit (amd64) computers support.
To add the PPA and install the package, press Ctrl + Alt +T on keyboard to open terminal and run 3 commands one by one:
sudo add-apt-repository ppa:ubuntuhandbook1/apps
sudo apt update
sudo apt install gnome-epub-thumbnailer
NOTE: The first command will asks for password authentication, though there’s no asterisk feedback. Just type in mind and hit Enter to continue.

- Arch and Manjaro Linux can install it via:
sudo pacman -S gnome-epub-thumbnailer

depends your system. For Arch, use sudo pacman -R gnome-epub-thumbnailer
.
Removing the package won’t clear existing thumbnail images, until you removed the content under “~/.cache/thumbnails
” either from file manager or by running command:
rm -R ~/.cache/thumbnails/*
