Broken dependencies while installing redmine using apt on fresh 14.04

Question

On vanilla 14.04:

1. run aptitude
2. chose package redmine
3. see broken conflicting package problem (something with ruby-rack)

How can I deal with it?

Answer 1

Run this command:

sudo apt-get build-dep package_name

or if you have synaptic, there is a filter for broken packages that you can see and then fix.
