Hello Linux Geeksters. As you may already know, Calibre is an open-source book management software, with many interesting features including e-book conversion, e-book viewer, library to ebook reader synchronization and support for the most popular eBook formats, including: epub, cbz, mobi, fb2 . Being multi-platform, the app works on Linux, Windows and Mac OS X.
The latest version available is Calibre 2.5.0, coming with the below improvements:
- E-book viewer: Allow changing the website that is used as a dictionary for looking up words in the viewer. Click the Preferences button in the viewer and choose the dictionaries tab to customize the website.
- Edit book/Book polishing: When embedding fonts or subsetting embedded fonts, handle the :first-letter and :first-line pseudo-element style rules.
And bug-fixes:
- Fix a typo preventing calibre from recognizing the new Kobo Aura H2O.
- Edit Book: Spell Check: Fix replaced words coming back into the list when toggling the “Show only misspelled words” setting.
- Edit Book: Spell Check: Fix replacing a word with multiple words causing the replacements to show up erroneously in the list of misspelled words.
- Edit Book: Fix leading or trailing hyphens on words being ignored when spell checking.
- E-book viewer: Fix a regression, caused by a Qt 5 behavior change, that caused incorrect colors to be shown when viewing MOBI files that use CSS 3 color specifications internally.
- MOBI Output: Handle input documents that use CSS 3 syntax for colors by converting the color to the #RRGGBB format required for MOBI.
- Tag Browser: Fix drag and drop of books onto a language not setting the language.
- Tag Browser: When renaming an item that is currently being searched for, remove the search indicator, as the search will no longer match the renamed item.
- Bulk metadata edit: Fix getting cover from EPUB files that have no cover image by rendering the first page as the cover not working.
- Custom cover generation: Fix disabled color schemes not being saved.
- Wireless device driver: Fix a regression in 2.4 that caused book matching to run slowly when connecting to calibre companion.

In this article I will show you how to install Calibre 2.5.0 on Ubuntu, Debian, Elementary OS, Deepin, Peppermint, Pinguy OS, LXLE, Linux Lite, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro and other Linux systems.
There is no repository available for Calibre 2.5.0, but the developers provide us a python oneliner for installing the latest Calibre version. So, to install Calibre on Linux systems, do:
$ sudo python -c "import sys; py3 = sys.version_info[0] > 2; u = __import__('urllib.request' if py3 else 'urllib', fromlist=1); exec(u.urlopen('http://status.calibre-ebook.com/linux_installer').read()); main()"
The installation script downloads and extracts the latest Calibre installer, and installs the app in /opt/calibre, by default. But the user can easily change the installation destination.
