Zammad from the sources under aaPanel

Hello Zammad team

I would like to install Zammad from the sources to run it together with aaPanel. aaPanel should then be responsible for the web server and certificates.

Unfortunately I have a problem with the installation.

Apparently the documentary is no longer the youngest.

Ruby 2.5.5 (see: should be used. Unfortunately, this is not available in Debian. How is this installed with the Debian package or which package.

Are the dependencies out of date:

Maybe someone here can help me get Zammad up and running.

Also here (see: I get tw errors that data cannot be written. Although I also assigned the extracted data to the user zammad: zammad.

ok if I want to install the standard Ruby from Debian 9 he would install me the 2.3.
How do you go about getting 2.5.5?

apt-get install ruby

Have ruby (2.3.x) as well as rake, bundler and rails
installed via apt.

Now when I run as user Zammad “gem install bundler rake rails” this one comes here!

zammad@vmd42762:~$ gem install bundler rake rails

Fetching: bundler-2.1.4.gem (100%)
ERROR: While executing gem … (Gem::FilePermissionError)
You don’t have write permissions for the /var/lib/gems/2.3.0 directory.

Ok I have now switched to CentOS 8 and installed aaPanel and ES.

I’m running Ruby 2.5.5 and if I now “gem install bundler rake rails”

then this message comes

[zammad@vmd42762 ~]$ gem install bundler rake rails

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

If you are upgrading your Rails application from an older version of Rails:

Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.

If you are starting a NEW Rails application, you can ignore this notice.

Even if I want to run it under aaPanel. It is a basic installation from the sources.

Finally, aaPanel only provides Apache or NGNIX.

Has nobody had this mistake yet?
