Thanks for the tip. That probably explains why there are so few complaints.
Edit: downloaded from link 1. then:
Code:
[roger@lenovo Bureau]$ sudo mkdir -p /opt/calibre && sudo rm -rf /opt/calibre/* && sudo tar xvf calibre-4.8.0-x86_64.txz -C /opt/calibre && sudo /opt/calibre/calibre_postinstall

Pretty quick download and install. I have the feeling though that I installed again Python 2.7... Well,it's working.
