KioskMode not working on armv6 on future3

[AlvinSchiller]

Describe your problem

Since Bullseye the installation fails on choosing option "KioskMode" on an armv6 device cause chromium-browser has no installation candidate.

What's your hardware set up?

Docker with armv6 qemu.
Raspberry Pi OS bullseye 32bit lite + bookworm 32bit lite

If possible, try to attach logs from ... (paths from RPi)

Setup Kiosk Mode
Install Kiosk Mode dependencies
E: Package 'chromium-browser' has no installation candidate
Configure Kiosk Mode

The package is called chromium vs chromium-browser, but wasn't this already the case for buster?

[AlvinSchiller]

chromium-browser
Don't know if it would work with just chromium as the code later calls also chromium-browser.

I get a Pi Zero 1 the next days, so i could then test this on the device.

Here I find only the package name chromium for all Debian versions and architectures https://packages.debian.org/search?suite=all&arch=any&searchon=names&keywords=Chromium

But this would mean it never worked... 🤔

According to git blame it was changed 3 years ago: https://github.com/MiczFlor/RPi-Jukebox-RFID/blame/03e64ff8680cd214f61fd56a2b6049c82b1b2d36/installation/routines/setup_kiosk_mode.sh#L18

chromium apparently has also no installation candidate for the armv6 platform

E: Package 'chromium' has no installation candidate

[s-martin]

Isn't armv6 (and armv7) rather armhf in Debian nomenclature?

[AlvinSchiller]

As far as i understood till armv6 it's armel and from armv7 it's armhf

[s-martin]

Googling provided mixed results, which architecture name matches which release name. 😏🫣🤔

I understand this means at least Raspian uses armhf for armv6 architecture?

There are or have-been at least two unofficial ports outside the Debian infrastructure.
Raspbian - Uses the hard-float version of the "new" ABI (EABI) like Debian armhf but targets v6 rather than v7. Currently tracks Debian jessie and stretch. Primarily but not exclusively targeted at the Raspberry Pi. GNU Triplet: arm-linux-gnueabihf

[AlvinSchiller]

Looks like. But that could mean it behaves different on a real pi.
I will test this as soon as I get the pi zero

I just installed chromium-browser on my Pi 1 successfully. My question would be, does it really make sense to actually offer Kiosk Mode on armv6 machines, cause it'll be pretty slow anyways. (the installation itself took 15 mins)
It uses armhf.

I didn't connect a screen yet to actually test it, it's just a wild guess.

Thoughts?

[s-martin]

Possible approach: detecting slow machines and then suggesting the user on slow machines to not install kiosk mode?

Minimum suggestion ARMv7?

Good to know its working and its "just" an emulation problem.
Thought of this too. As of what I read it was discontinued for armv6 as it was nearly unusable slow.

I would also suggest either don't offer this feature for armv6 devices or give a warning that it can be slow, like other features/installations already do.

Maybe depends if it would still be usable ? @pabera ?

[AlvinSchiller]

I tested this on a Raspberry Pi Zero 1 W and the installation was succesfull.
So the inital reported error is just the case for the ci tests and docker. Probably because of the unofficial ports described above.

BUT after startup the UI show an error "chromium is supported on Raspberry Pi Zero W". So it seems its nevertheless unsupported for arm6 devices.
@pabera could you verify this for the Pi 1? I used the official develop branch on bullseye.

I think we should add this, but give the message that its not supportedf on this device model and can't be installed.
I would not just leave it out, as users might ask, why this is not available.

yeah, let's add this, so users know that it will not work

so this issue is a wontfix

[AlvinSchiller]

Would it be desired to fix this with another browser?
Some suggest dillo as replacement, but i dont know if there are any tutorials.

[pabera]

Let's not go this route now. We can create an issue to investigate dillo another time.
