Installing openwisp2 to a raspberrypi 4

[Sinh Ta]

Hello,

I'm trying to install openwisp2 to a raspberry pi 4 to set it up as a wlc for a couple of openwrt routers. And everything went well until the installation of openwisp2 controller and its dependencies. The error message (attached below) indicates some invalid version, but I couldn't figure that out.

I'm just wondering if you can help me to eradicate the issue. Many thanks in advance.

Hi,

Hmm, It's an unexpected error, looks like a problem with dependencies of openwisp-controller.

1. I would suggest trying on a fresh install.

2. If that doesn't help, could you please try debian?  https://raspi.debian.net/

3. Could you try manually locking openwisp-utils version? (openwisp2_utils_pip: -e https://github.com/openwisp/openwisp-utils/tree/0.7.0#egg=openwisp_utils[rest])

If the 3rd trick works or If these tricks don't help, please let us know. I'll try to install on my Pi and check it out! :-)

Best,

Ajay T.

Hi,

I ran it on my Pi,

I changed your playbook to the following:

```

- hosts: raspi

become: true

roles:

- ansible-openwisp2

vars:

openwisp2_default_from_email: "openwisp@{{ inventory_hostname }}"

openwisp2_notifications_pip: true

openwisp2_notifications_delete_old_notifications: 60

openwisp2_celery_broker_max_tries: 10

openwisp2_network_topology: true

openwisp2_extra_python_packages: [bpython]

openwisp2_language_code: "it-it"

openwisp2_time_zone: "UTC"

openwisp2_ssl_state: "Italia"

openwisp2_ssl_locality: "Matera"

openwisp2_ssl_organization: "Ninux Basilicata"

openwisp2_http_allowed_ip: "10.8.0.0/16"

# Variabili per nginx

openwisp2_nginx_ipv6: true

openwisp2_nginx_spdy: true

openwisp2_nginx_ssl_config:

gzip: "on"

gzip_comp_level: "6"

gzip_proxied: "any"

gzip_min_length: "1000"

gzip_types:

- "text/plain"

- "image/svg+xml"

- "application/json"

- "application/javascript"

- "text/xml"

- "text/css"

- "application/xml"

- "application/x-font-ttf"

- "font/opentype"

```

Two things:

1. I don't know why did you set the `_pip` as `true`, these options want link from where you want to install your custom openwisp project.

2. I faced a problem version mismatch problem while installation, I solved it by `sudo apt-get install python3-cffi` if you face that on the step [openwisp.openwisp2 : Install openwisp2 controller and its dependencies], try it, let me know if that works out.

Best,
Ajay Tripathi

Hello Ajay,

Wow, thank you very much for such effort! I really appreciate your help.

I follow the installation instructions (https://openwisp.io/docs/user/quickstart.html#install-the-openwisp-2-server) and install openwisp2 to the Pi, which was running debian buster 64 from my linux mint (a derivative of ubuntu).

In the instruction, after installing ansible and git, I also install the role 'ansible-galaxy install openwisp.openwisp2', which matches that of the playbook.yml file (line 4, in the instruction). You mention in the playbook.yml the role 'ansible.openwisp2', would that have any ... consequences!? Also my playbook.yml is just like that of the installation instruction, would that .. cause any issue!?

I'm not quite sure where I would have set the '_pip' as 'true', since I just strictly followed the instructions. Although, I did upgrade pip to the latest version prior to the installation (

Last weekend, I replaced the os on the Pi with Ubuntu 20.04, it took quite a bit longer to install but still got error messages, albeit different ones, and a super long one! I attached the log file here.

I'll try to replace the os on the Pi this weekend with Debian Buster again, and try your suggestions, see how that goes. I'll keep you posted.

Again, many thanks for your help and best regards,

Sinh

Hi,

please use openwisp.openwisp2, I am working on the development version from Github master not the released one, hence that's just a development difference. `openwisp.openwisp2` is the released version.

Although, I did upgrade pip to the latest version prior to the installation

Thaat should be fine.
 

and a super long one! I attached the log file here.

Can you please try doing `sudo apt-get install python3-cffi` on your Pi, that should fix the error.

if not can you please send me the installed version, I'll try it out for that.

Also, If I am not wrong, Ubuntu 20.04 brings some changes and the released version was for Ubuntu 18.04, that might cause problems.

If you want to use Ubuntu 20.04, try using the version from GitHub master branch itself.

Best,

Ajay Tripathi

Hi Ajay,

I got pass that error, but now I got a new error that I can't figure out from the below step. I couldn't find any of those zip files those in the Pi, just wondering if you could give me some clues!? Thanks,

Hi,

I think the `source env/bin/activate` command did not work, can you please double check if the python virtual environment is activated.
You terminal would look like `(env) pi@raspberry-pi:/opt/openwisp2 $` if it works successfully!

Hello Ajay,

Sorry, I was just too busy during the day! So a bit late in replying.

When I manually run the command that you stated, it works! Please see below

Ajay,

Just rebuilt my Raspberry Pi with ubuntu 20.10 and re-do the installation again. I still get the python2-cffi error, since the installation process expecting the package python3-cffi-backend on the Pi to be at least version 1.14.4-0, and the command running the command 'apt install python3-cffi-backend' doesn't really help within the distribution, since it keeps downloading the same version (1.14.2-1 in ubuntu 20.10). I have to change the /etc/apt/sources.list to add the hirsute repository which include python3-cffi-backend version 1.14.4-1 that satisfies the condition for installation of openwisp2. That went well, but now I have a new error at the "migrage" step, which indicating that it doesn't find the module 'celery', just wondering if you can help troubleshoot that!? Error message below.

Thanks for your help

Hi Sinh,

Three things I noticed:

1. The package I recommended earlier was `sudo apt-get install python3-cffi`` not `python2-cffi`, openwisp doesn't work or depend on python2 anymore but I think the package you found (python3-cffi-backend) gets the job done as well! :-)

2. In the output that you send:

```

pi@raspberry-pi:~ $ cd /opt/openwisp2
pi@raspberry-pi:/opt/openwisp2 $ ls

db.sqlite3  env  generate_django_secret_key.py  log  manage.py  openwisp2

pi@raspberry-pi:/opt/openwisp2 $ source env/bin/activate

(env) pi@raspberry-pi:/opt/openwisp2 $

``

I mean't do the `python manage.py migrate` after the (env) is visible, like:

```

(env) pi@raspberry-pi:/opt/openwisp2 $ python manage.py migrate

<send-output-of-this-command>

```

Finally, 

3. In the latest logs that you've send, this is odd. celery should have been already installed.

3.1 Can you please share your playbook?

3.2 Can you please ensure that you have the latest version of ansible-openwisp2 released on 12th December?

Hello Ajay,

I've managed to install it on the Pi with ubuntu 20.10, ubuntu seems to give a bit less trouble than debian. And it's great, really! Pretty cool stuff! Thanks for the tool, although I've got to admit this is one of the toughest software installations that I've ever done. My openwrt routers register beautifully, and I can see them all on the controller!

I'll have to back up the Pi's micro sd card just in case and my next task will be to mesh my routers through openwisp. If you could please point me to where I can find the information on that, it'd be a great help.

Again, thanks for all your help and for a very useful network controller.

Hi,

> ubuntu seems to give a bit less trouble than debian.

Interesting. I haven't tried ubuntu, but if that is easier to use, I'll recommend that one to folks installing openwisp for the first time.

> this is one of the toughest software installations that I've ever done.

I have a couple of ideas to make docker-openwisp installation even easier an conflict free in the future, let's see how that turns out but ansible-openwisp2 will need atleast some technical expertise here and there!

> my next task will be to mesh my routers through openwisp. If you could please point me to where I can find the information on that, it'd be a great help.

This might help: https://openwisp.io/docs/user/configure-device.html#compile-your-own-openwrt-image

Best,
