Hello everyone. I followed all the steps indicated in https://github.com/openwisp/ansible-openwisp2#usage-tutorial for  the installation of Opewisp2, therefore:

 

  • hi I have a virtual machine Debian 10.8 (Buster) called  Debian-srv with ip 172.16.0.211 on Hyper-v  of my win10 pc with ip 172.16.0.104

 

  • on this Debian machine I have enabled  ssh access to the root user by editing the / etc / ssh / sshd_config  file and replacing  the line #PermitRootLogin prohibit-password with the line PermitRootLogin yes

 

  • on my pc i have installed Cigwin

 

  • Using Cygwin I installed Ansible, Git and joe

 

  • Using Cygwin  I have installed the Openwisp  role running the command

ansible-galaxy install openwisp.openwisp2

 

  • Using Cygwin  I chose and created a Working Directory called:

openwisp2-ansible-playbook

 

  • Using Cygwin  I created an inventory file called host with the following  content:

                [openwisp2]

debian-srv

 

- Using  Cygwin  I created a playbook file called playbook.yml with the following  content:

           - hosts: debian-srv

become:

roles:

     - openwisp.openwisp2

vars:

openwisp2_default_from_email: "open...@openwisp2.mydomain.com"

 

  • Using Cygwin i launched  the playbook to install Openwisp on the server by running the following command:

 ansible-playbook -i host playbook.yml -u root -k

 

 

Below the output that comes out to me:

 

 

 

Obviously  Openwisp is not reachable on the Debian machine at https://debian-srv/admin

 

Thanks in advance

Hi, 

it's complaining that it cannot install the postfix package, but this looks like a system issue rather than an OpenWISP issue.

What happens if you try to install the postfix package manually?

In the development version there's a config option to disable the installation of postfix, in case this helps.
You would have to set an external SMTP to make email sending work though.

Best regards
Federico

ok, I'm trying to manually install Postfix. To do this I have to install mailutils first. When I run:

 

sudo apt install mailutils

 

I get the following error:

 

E: Could not find the mailutils package

 

Maybe it's a source problem from which to get the installation packages? Does it refer to E: which maybe is the cd player, corresponding  to the installation iso with which I created the Debian virtual machine?

If yes, how to remove E. from the installation sources?

 

thanks

I'm not sure how to help, I never had this issue with Debian. I suggest asking in the support channels / forums of Debian.

Hi, the Linux version is Debian 10.8 (Buster). I tried to perform a install the development version of the playbook  using the following steps::

 

  • in the openwisp2-ansible-playbook folder I created a roles subfolder and placed myself in it

 

  • I have cloned ansible-openwisp2 and Stouts.postfix

  git clone https://github.com/openwisp/ansible-openwisp2.git openwisp.openwisp2

    git clone https://github.com/nemesisdesign/Stouts.postfix

 

  • I edited the playbook.yml file by modifying it as follows:
 

- hosts: debian-srv

  become:

  roles:

    - openwisp.openwisp2

  vars:

    openwisp2_postfix_install: false

 
-          Then I launched the Playbook using the command:
 
  ansible-playbook -i hosts playbook.yml -u root -k
 
Unfortunately, I still find another error that I report below.

It looks like postfix is giving you troubles on this system, which is unusual. What version of debian is this? We tested this playbook up to Debian buster.

 

Why don't you just install the development version of the playbook and turn off the installation of postfix by setting openwisp2_postfix_install: false ?

This should allow you to test the system and fix the postfix issue later on if you need.

 

Ciao

Federico

Hi,

For the first error, try looking for postfix:
```
apt update
apt-cache madison postfix
```

If the first command returns nothing then, postfix is available in the following repositories:
```
http://deb.debian.org/debian buster/main amd64 Packages
http://deb.debian.org/debian buster/main Sources
```

Please add them in your sources and try again.


For the second problem, try updating pip:

```
sudo python -m pip install --upgrade pip
```


Best,
Ajay Tripathi

Hi, for the postfix problem, i have installed a development  version of the playbook  with which I ignored the installation of the postfix package.

Using the command python -m pip -V, I saw that the version of pip installed is 21.0.1

 

When I launch the Playbook using the command:
 
  ansible-playbook -i hosts playbook.yml -u root -k
 

 

The first problemi is the following:

These look like system issues, it's weird that you're getting so many of them, the installation runs smoothly for me on Debian, where are you getting the image from?

Anyway, sometimes problems arise, in these cases you have to look on google, for example, I googled the error message in the ansible output and found this: https://stackoverflow.com/questions/43325110/exception-version-mismatchcffi
Try the same approach if you encounter other issues.

Hi Federico, but as these are virtual server platforms, I can also use a different Linux version.

For example I could use Ubuntu Focal (20.04) which I tried to use many months ago but was not yet fully supported. Or is it better to play it safe with Bionic (18.04.2) ?

Thank you

Hi, I installed OpenWisp2 on Ubuntu Focal (20.04) and it was finally successful! Now I just have to move on to the study phase of the configuration part.

Thank you
