Questions[redmine](ubuntu)

I'm trying to configure plugin in redmine after getting a github link of the plugin it's installed successfully and these command running smoothly as:

sudo gem update
sudo gem install bundler
sudo gem update --system
sudo gem pristine bundler

but I'm getting this error when I write

sudo bundle update rake

after this command I'm getting the error and screenshot is attached.

Bundler could not find compatible versions for gem "actionpack":

In snapshot (Gemfile.lock):

actionpack (= 4.2.10)

In Gemfile:

rails (~> 4.2.8) was resolved to 4.2.10, which depends on
  actionpack (= 4.2.10)

rails-controller-testing (~> 1.0.4) was resolved to 1.0.4, which depends on
  actionpack (>= 5.0.1.x)

Running bundle update will rebuild your snapshot from scratch, using only the gems in your Gemfile, which may resolve the conflict.

I hope someone knows the solution to it.

I have RVM and it's default ruby is 2.0.0 systemruby was 1.8.7 before and somehow my newly installed redmine 2.4.3 application tries to look for the old folder (1.8) instead of my 2.0.

That's my apache2 error log. :

*** Exception LoadError in PhusionPassenger::Rack::ApplicationSpawner (no such file to load -- bundler/setup)

I read that I can have different ruby setups in the apache2 config like this :

    PassengerRuby /home/me/.rvm/rubies/ruby-2.0.0-p247/bin/ruby
    PassengerRoot /home/me/.rvm/gems/ruby-2.0.0-p247/gems/passenger-4.0.37

when I have set AllowOverrid all

What do I miss to make this work ?

I am trying to install a new version of redmine on my server. Right now I have redmine 1.3.2 and I installed 2.4.3

But passenger can't open my application and I get this error :

I have different rubies installed by accident. But I don't want to change it, since other applications are using ruby and I don't want to screw up anything.

Right now my RVM says that my ruby used is version 2.0.0 (using RVM LIST)

If I go for which -a ruby the output is this :

/home/me/.rvm/rubies/ruby-2.0.0-p247/bin/ruby
/home/me/.rvm/bin/ruby
/usr/bin/ruby

so I tried to run a different ruby defined in my apache2. Using the official guide from passenger. But when I place in my apache this line :

PassengerRuby /path/to/my/ruby

I get an error "PassengerRuby not allowed to set here"

How can I use my ruby 2.0.0 for the new redmine? It now points to a 1.8 version as in screenshot provided

I have a redmine setup. today morning I saw that my redmine folder was empty and I was unable to access redmine, so I tried installing redmine again using:

sudo apt-get install redmine

I am getting the following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
  redmine: Depends: ruby-rails-2.3 (>= 2.3.14) but it is not going to be installed or rails (>= 2.3.14) but it is not going to be installed

How can I reinstall redmine?

I recently installed ssmtp on my server to enable e-mail notifications for a redmine install. While I was verifying everything was setup correctly I got an e-mail notification about a failed cron job. This turned out to be really helpful and I never would have noticed it had I not set this up.

It's been a few days since and I haven't received any other e-mails from the system. By default, what mail gets sent to root?
