Kicad 8 on raspberry pi

When will Kicad 8 be available for Raspberry pi.

Thanks in advance

Which model? There are so many. I’m pretty sure, for example, that it will not run on my ancient RPi 1.

Debian bookworm-backports has 8.0.7 for the arm64 and armhf architectures. Debian -- Details of package kicad in bookworm-backports

the model that I am using is 4.

If you run Raspberry Pi OS just type:

sudo apt install kicad

in a terminal.

that installs kicad 6

You can install the latest KiCad version (currently 9.0.0) from bookworm-backports.

Ensure that you have backports enabled by going to Raspberry Menu → Preferences → Add/Remove Software. Then click the Options menu → Package Sources… and check the box beside Debian Bookworm Backports

Next open a Terminal window and update the package information to get the latest backports packages:

sudo apt update

To see the available kicad versions you can ask apt to list all versions:

apt list -a kicad

On my system I currently see these versions:

Listing... Done
kicad/stable-backports 9.0.0+dfsg-1~bpo12+1 arm64
kicad/stable,now 6.0.11+dfsg-1 arm64 [installed]

kicad/stable-backports 9.0.0+dfsg-1~bpo12+1 armhf
kicad/stable 6.0.11+dfsg-1 armhf

You can then install the latest KiCad from backports using this command:

sudo apt install kicad/bookworm-backports

For completeness I should also mention that you could install the KiCad Flatpak using the instructions at Install using Flatpak | KiCad EDA to install KiCad 9 on Raspberry Pi.
