Compatibility issue between hailo-all 4.20 and manually installed 4.19 components on Raspberry Pi

General

Hi Hailo team,

I’m trying to install a project on a Raspberry Pi that requires Hailo version 4.19.
At first, I ran the usual command:

sudo apt install -y hailo-all

But this installed version 4.20.0, which causes incompatibilities with my code.

So I tried downgrading manually with:

sudo apt install -y --allow-downgrades \
  hailo-tappas-core=3.30.0-1 \
  hailo-dkms=4.19.0-1 \
  hailort=4.19.0-3

However, when I run:

hailortcli fw-control identify

I get the following error:

[HailoRT] [error] CHECK failed - Driver version (4.20.0) is different from library version (4.19.0)
[HailoRT] [error] Driver version mismatch, status HAILO_INVALID_DRIVER_VERSION(76)
...

I double-checked the installed versions using:

apt-cache policy hailo-tappas-core
apt-cache policy hailort
apt-cache policy hailo-dkms
apt-cache show hailo-all

It seems that while the components are properly downgraded to 4.19, the hailo-all meta-package remains at version 4.20, which might be pulling in conflicting dependencies or keeping older drivers in place.

I’m looking for a way to cleanly install only version 4.19 for everything, or to downgrade hailo-all to version 4.19 — but I can’t seem to make that work.

Any advice or official guidance on how to proceed would be greatly appreciated!

Thanks in advance

I tried what is recommended :

i changed : `sudo apt install -y hailo-all
sudo apt install -y --allow-downgrades hailo-tappas-core=3.30.0-1 hailo-dkms=4.19.0-1 hailort=4.19.0-3

by sudo apt install hailo-tappas-core=3.30.0-1 hailort=4.19.0-3 hailo-dkms=4.19.0-1 python3-hailort=4.19.0-2 and sudo apt-mark hold hailo-tappas-core hailort hailo-dkms python3-hailort

I tried to do it on a freshly installed raspberry os but i still got hailortcli fw-control identify [HailoRT] [error] CHECK failed - Driver version (4.20.0) is different from library version (4.19.0)

I doubled checked and when i do : dpkg -l | grep hailo
I have :

hi  hailo-dkms                            4.19.0-1                            all          Hailo PCIe driver
hi  hailo-tappas-core                     3.30.0-1                            arm64        This package contains the core components of the Hailo Tappas platform.
ii  hailofw                               4.20.0-1                            all          Hailo firmware
hi  hailort                               4.19.0-3                            arm64        HailoRT
hi  python3-hailort                       4.19.0-2                            arm64        HailoRT Python API, which wraps the runtime library

so ii hailofw is 4.20 and not 4.19 thats probably the problem but i dont know how to solve it
