Vim Syntax Highlighting does not work

Question

I\'ve installed a fresh Arch Linux system on my laptop and downloaded the vim package.

I haven\'t altered the .vimrc file, but the syntax highlighting doesn\'t seem to w

On my Ubuntu 18.04 system i.e. c-highlighting works but Icinga2 config file highlighting being provided by the vim-icinga2 package does not. Quote from https://packages.debian.org/sid/vim-icinga2:

As per the Debian vim policy, installed addons are not activated automatically, but the "vim-addon-manager" tool can be used for this purpose.

Executing vim-addon-manager -w install icinga2 following a regular vim-icinga2 package installation solved the issue. The -w option forces a system wide rather than a just per current user activation. Notice that executing vim-addon-manager without arguments yields a list of 39 modes being disabled by default:

> vim-addon-manager
# Name                     User Status  System Status 
align                       removed       removed       
alternate                   removed       removed       
                        ...
icinga2                     removed       installed    # Due to above command
                        ...

If you do miss highlighting chances are your mode is among this list.

NB: Ubuntu 18.04 seemingly inherits Debian's policy. None of the above answers solved my issue. No ~/.vimrc configuration or manual activation was being required after the above described activation.
