fresh install fails (some debugging inside)

[iameru]

Inspired by the talk at rc3 about this project I wanted to try it out.

after a fresh installation on raspbian buster (tried bullseye where at least the backend and frontend ran until meeting import errors, remembered the speaker at rc3 said buster would work better) the thing did nothing. login shows:

systemctl status tinycheck-watchers:
    ...
    ModuleNotFoundError: No module named 'sqlalchemy'

systemctl status tinycheck-frontend:
    ...
    ModuleNotFoundError: No module named 'flask'

systemctl status tinycheck-backend:
    ...
    ModuleNotFoundError: No module named 'flask'

apparently line 320 might not have worked?

 python3 -m pip install -r "$SCRIPT_PATH/assets/requirements.txt"

My try python3 -m pip install -r requirements.txt revealed an error (multiple similar all with cryptography package)

  Failed building wheel for cryptography

debug assistance of pip(?) recommends upgrade.

python3 -m pip install --upgrade pip

and again, somewhat more compact:

This package requires Rust >=1.41.0.
----------------------------------------
ERROR: Failed building wheel for cryptography
Failed to build cryptography
ERROR: Could not build wheels for cryptography, which is required to install pyproject.toml-based projects

So this might have to do with cryptography from version 3.5 onwards relies on rust >=1.45.
https://cryptography.io/en/latest/installation/

edit requirements.txt

cryptography < 3.49

which made the install ( python3 -m pip install -r requirements.txt ) go through

enough for today

now the web backend and frontend work-

still, like in the bullseye test I did earlier it is stuck at creating wifi network forever ( /generate-ap url )

[iameru]

ok. some more info. as you write in https://github.com/KasperskyLab/TinyCheck/wiki/Timeout-on-the-web-interface you are happy about bugreports.

when debugging and starting the frontend myself the error now is:

I’m also inspired by the r3c-talk.
On my raspi3 I startet as follow:

clean install image: Raspberry Pi OS (Legacy) from 2021-12-02 (buster) with Imager
over ssh, do the installation as described here on github as root

kioskmode doesn't work immediately because tinycheck-kiosk was looking for chromium-browser, I only have chromium, I set a symbolic link.

Now everything is working except the PDF Export. I tried the commands as described in #78 but with no success.
Always get: function/symbol 'pango_context_set_round_glyph_positions' not found in library 'libpango-1.0.so.0': /lib/arm-linux-gnueabihf/libpango-1.0.so.0: undefined symbol: pango_context_set_round_glyph_positions

@fosBHY which hardware are you using? I have a zero w available for some testing (buster image) and can confirm the problem with the cryptography packet which you've fixed. Additionally, on the zero w, which is armv6 hardware, the nodejs installation is incompatible and returns an error because it detects the armv6 hardware (Message: ## You appear to be running on ARMv6 hardware. Unfortunately this is not currently supported by the NodeSource Linux distributions. Please use the 'linux-armv6l' binary tarballs available directly from nodejs.org for Node.js 4 and later."). I've installed v11.15.0 manually from nodejs.org, which seems to be the latest tarball with v6 support and now at least it starts to build. But it breaks with Error: @vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree. No time left to investigate any furhter for now...

From my point of view the installer is broken in several ways depending on different circumstances like hw-versions etc. For non technical people it seems pretty hard to get around that and I would suppose that creating and hosting an raspi image would make much more sense.

[iameru]

I used a raspberry pi 3b+

I second your view on the installer and also think a dedicated Image would be much easier for people to actually use, even nonsavvy

[unmerkbar]

Hi there.

Wanted to join the discussion. Same for me, inspired by the rC3 Talk...

I have an Raspberry Pi 4 Model B Rev 1.2 with a new Image of Buster by the Raspi Imager and did the installation as described in the wiki. No errors during installation. I access the front-end via browser within the home network. It stucks at the same point when generating the AP on the /generate-ap url. Enabling the debug mode showed the same ModuleNotFoundError as described in #90 (comment) by @fosBHY.

I had many issues trying to install this on the newest version of rpi os (debian 11).

The install script needed a little love (maybe needs a little more).
I also used a venv for python and and systemd.

If anybody would like to help test it I'd appreciate it.

[cyb3rwr3ck]

I had the chance to get my hands on a rpi zero w 2 which has the correct hardware base (ARM7). The build process works correctly but still it needs the installation of libopenjp2-7-dev, libpangocairo-1.0-0 and pip3 install -U django-weasyprint to fix the other bugs related to missing dependencies. Additionally a rfkill unblock 0 was necessary.

Hello to everyone!

We did some work on installer script recently.
For now it runs with no issues (almost :-) ).

Any issues with versions and deps were fixed also, so for now it seems like this issue can be closed.
