Cannot install bickd on PI rasbian trixie

[Pat28]

Hi ,

I put the latest trixie image with desktop on a raspberry pi 4.

When i try to install brickd ,after made the latest update and upgrades, 

with sudo apt install brickd

i receive an error with libgpiod  version 2 not supported in trixie. 

and i cannot install brickd with libgpiod 3version 3.

Can you tell ne if there is a fix/work around to install brickd on trixie  rasbian.

Thanks

Patrick

You can try this:

• Download libgpiod2_1.6.3-1+rpi1+b2_armhf.deb
• sudo dpkg -i libgpiod2_1.6.3-1+rpi1+b2_armhf.deb
• If there are errors, run sudo apt install -f
• Install brickd

Hi, 

I downloaded your link to libgpiod2 1.6.3 and run sudo dpkg -i libgpiod2_1.6.3-1+rpi1+b2_armhf.deb without success:

Then install brickd

And it is not working.

 Any other idea?

I forgot that you might still have libgpiod3 installed from a previous installation attempt.

If you don’t have anything that depends on libgpiod3, remove it first and then try again with libgpiod2.

Hi,

as libgpiod3 is preinstalled with Raspbian Trixie i see the solution to replace it with an older version only as workaround.

Is there already a plan to replace libgpiod2 with the latest version as dependency for Raspbian Trixie?

KR,
Max

Yes, but there’s no ETA for that yet. (See below.)

New brickd version to work with libgpiod2 and libgpiod3 coming this week.

[photron]

Fixed brickd 2.4.8 is released. Please try "sudo apt update" and "sudo apt install brickd" again.

Works on my installation (Raspberry Pi Zero 2W). Thank you

[Pat28]

Ok, it is working now with trixie on raspberry 2B

Thanks
