How to Install ONLYOFFICE on Ubuntu 18.04

ONLYOFFICE Desktop Editors is a free and open source office suite, distributed under GNU AGPL v.3.0., available for Linux, Windows and Mac OS. It offers three editors included in one package: for text documents, spreadsheets and presentations.

The benefits offered by ONLYOFFICE Desktop Editors run as follows:

• tab-based user interface to deal with multiple files within one and the same window

• compatibility with MS Office and Open Document formats

• support for the third-party plugins (for example, ClipArt, OCR, Speech, Symbol Table, Translator, YouTube, etc.)

• connection to the cloud platform of your choice: ONLYOFFICE, Nextcloud or ownCloud, offering real-time collaboration on documents for remote teams

• end-to-end encryption to protect documents, including temporary files, with the AES-256 encryption algorithm. Blockchain technology with asymmetric encryption was implemented for reliable password storing and transferring.
