Rails wikedPDF Error: PDF could not be generated – CentOS

I’m trying to use WickedPdf on rails 6 but I’m having this error

RuntimeError (Failed to execute:
["/home/guilherme/.rbenv/versions/2.7.1/bin/wkhtmltopdf", "file:////tmp/wicked_pdf20200531-14069-p9pvre.html", "/tmp/wicked_pdf_generated_file20200531-14069-8mk29k.pdf"]

):

in my gemfile i add

gem 'wicked_pdf'
gem 'wkhtmltopdf-binary'

my controller method to render pdf is

  def gera_contrato
    cliente = Cliente.find_by_id(params[:cliente])
    @cnpj = cliente.local.cnpj
    @razao = cliente.local.razao
    @fantasia = cliente.local.fantasia
    @nome = cliente.nome
    @cpf = cliente.cpf
    @rg = cliente.rg
    render pdf: 'contrato', handlers: [:erb], formats: [:html]
  end

my html file to pdf is

<!doctype html>
<html>
  <head>
    <meta charset='utf-8' />
    <%= wicked_pdf_stylesheet_link_tag "pdf" -%>
  </head>
  <body>
    <h1><%= @cnpj %></h1>
    <h1><%= @razao %></h1>
    <h1><%= @fantasia %></h1>
    <h1><%= @nome %></h1>
    <h1><%= @cpf %></h1>
    <h1><%= @rg %></h1>
  </body>
</html>

I already changed the paths, changed gem versions, and did a lot of things but nothing worked, what should I do to solve this error?

    Well, there is your problem. The error message states: Invalid platform, must be running on Ubuntu 14.04/16.04/18.04. You’ll have to install the version for Ubuntu 20.04 from https://wkhtmltopdf.org/downloads.html and manually point it to this version like this

    /config/initializers/wicked_pdf.rb

    WickedPdf.config = {
  exe_path: '/path/to/correct/version'
}

    I faced the same error, and after doing some research I found the issue is due to wkhtmltopdf-binary, which was not compatible with Ubuntu 21.04 (in my case). Found the solution here.

    Option 1:

    gem 'wkhtmltopdf-binary', '~> 0.12.6.5'

    Option 2:

    sudo apt-get install zlib1g fontconfig libxrender1 libfreetype6 libxext6 libx11-6 

sudo apt-get install wkhtmltopdf
