How to completely uninstall phusion passenger in Ubuntu 13.10, Apache2 combination?

Question

I installed the Phusion Passenger using the below commands

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7
sudo apt-get install apt-transport-https ca-certificates

Then, because of some reason, I tried to uninstall Phusion Passenger by the following way, First: I removed the all Phusion Passenger configuration directives Than: gem uninstall passenger

(results: gem "passenger" is not installed)

If I put "passenger -v". It returns

Phusion Passenger version 4.0.37
"Phusion Passenger" is a trademark of Hongli Lai & Ninh Bui.

Still it is not completely removed. I don't know how to proceed further.

I want to completely remove the Phusion Passenger, and install the fresh copy. Please assist me to do this

Read this modrails.com/documentation/…, which is not very hard to find. Uninstalling through the same tool you used to install (so use apt-get) – Shuster

They didn't gave any procedure to uninstall through APT – Cytoplasm

I was actually installed through APT – Cytoplasm

So you ran sudo apt-get uninstall PACKAGE NAME – Gustatory

I tried sudo apt-get uninstall libapache2-mod-passenger. It through error like this : Invalid operation uninstall – Cytoplasm

from #7833005 "If you installed Phusion Passenger via a gem, then type gem uninstall passenger. You might have to run this as root. If you installed Phusion Passenger via a source tarball, then remove the directory in which you placed the extracted Phusion Passenger files. This directory is the same as the one pointed to the by 'PassengerRoot' configuration directive." – Gustatory

I tried both the ways. but understand dude.I was installed through APT. – Cytoplasm

It's apt-get remove, not apt-get uninstall. Pass the same package name that you passed to apt-get install. – Emmettemmey

I find out the answer dude.."sudo apt-get purge passenger" – Cytoplasm

I obvious made a mistake, it is not 'uninstall', I had one of those moments it is remove. – Gustatory

Ok diek..I really thanks for interested in my question. – Cytoplasm

Answer 1

A friend had the same problem:

• apt-get remove passenger gave "passenger is not installed"
• gem uninstall passenger gave "passenger is not installed"
• passenger -v shows it is installed

The reason is that she had installed passenger with Ruby 1.9.1 and since upgraded to Ruby 2.1.5. (note: rvm was not installed).

The answer is to gem1.9.1 uninstall passenger which prompts if you want to remove the gem and packages or just the gem.

Answer 2

should be able to run:

apt-get purge (I used passenger)

I hope this helps!

As should apt-get remove, but remove won't touch related configuration files, purge deletes some of them (which are not at home dir). – Shuster
