I've installed gem install passenger for my rails app. Now I try passenger-install-apache2-module.
I get errors screen:
Installation instructions for required software
- To install Apache 2 development headers: Please run apt-get install apache2-prefork-dev as root.
- To install Apache Portable Runtime (APR) development headers: Please run apt-get install libapr1-dev as root.
- To install Apache Portable Runtime Utility (APU) development headers: Please run apt-get install libaprutil1-dev as root.
When I run sudo apt-get install apache2-prefork-dev, I get
The following packages have unmet dependencies: apache2-prefork-dev : Depends: apache2.2-common (= 2.2.22-1ubuntu1) but 2.2.22-1ubuntu1.1 is to be installed.
E: Unable to correct problems, you have held broken packages.
When I run sudo apt-get update, it doesn't solve anything. The error still exists.
