Install Calibre eBook Reader on Ubuntu. Calibre 3.0 released with new Content server, support for High Resolution (Retina) screens and conversion to Microsoft Word (DOCX) feature.
Prominent features of Calibre 3.0 are:
New Content server – The Content server allows you to wirelessly browse your calibre books on any modern phone/tablet and even read the books right in your phone browser. You can start the Content server by clicking the Connect/share button in calibre. Then just open up a browser and type http://localhost:8080 in the address bar. You will see a list of calibre libraries. Click on one and browse the books. Click on a book and you will have the option to read or download it.
Support for High Resolution (Retina) screens- A much requested feature. As of calibre 3, calibre now natively supports high resolution (Retina) screens. It should auto-detect when it is started up on such a screen and adjust itself accordingly. It can be controlled via Preferences → Look & feel → Adjust for high resolution screens.
Support for icon themes and a new default icon set – calibre now has support for installing different icon themes (Preferences → Look & feel → Icon theme). There are many different icon themes to suit different tastes. In addition, to celebrate calibre’s tenth birthday, which was in October, 2016, the default calibre icons have been changed. Never, fear if you prefer the old icons they are also available, as an icon theme.
Conversion to Microsoft Word (DOCX) – calibre can now convert all the book formats it supports to Microsoft Word (DOCX) files. Alongside the support for conversion from Word, you can now go back and forth between Word documents and e-book formats to your hearts desire.
