Calibre gives broken dependencies when installing [solved]

[dbyentzen]

Another option would be to try using aptitude instead of aptget. Aptitude is more intelligent than apt-get and can handle downgrading or removal conflicting packages for you, but it will also make a series of recommendations based on different working scenarios for you to chose from.

Code:

aptitude install calibre

I installed and tried aptitude with no luck---I asked it to "try harder" twice:

david@david-Inspiron-660s:~$ sudo aptitude install calibre

I don't *need* Calibre but I do need a ebook reader able to handle different formats. Do you know of Lucidor or another ebook reader?
