Missing dependency: dpkg-checkbuilddeps: error: unmet build dependencies: dh-dkms

[dan-s-github]

First of all, big thanks to providing this script to simplify installation

After struggling to install the coral tpu using the getting started instructions I landed here.

Steps executed:
Copied the script to my frigate box

chmod +x install_coral_tpu.sh
sudo ./install_coral_tpu.sh --install

install failed to compile as dh-dkms was missing

Switched to branch 'pr-50'

after installing the missing dependency everything worked fine

sudo apt install dh-dkms
sudo ./install_coral_tpu.sh --install

Hi @dan-s-github ,

I can confirm the same error. I'm having problems making it work after installing the missing dependency though. Can you maybe help me find out if I missed something?

After installing dh-kms, the --install command works, but the status doesn't show as expected:

Coral TPU PCIe hardware not detected (lspci | grep 1ac1:089a).
Apex devices not found in /dev.
DKMS Gasket module: gasket/1.0, 6.12.41+deb13-amd64, x86_64: installed
Apex module not loaded.
libedgetpu1-std version: 16.0

Non-root access:
Udev rule for non-root access: not present.
Apex group for non-root access: not present.
Driver installation validation failed.

I do see an error in the logs while installing:

Now running lintian gasket-dkms_1.0-18.4_amd64.changes ...
running with root privileges is not recommended!
**E: gasket-dkms changes: bad-distribution-in-changes-file noble
W: gasket-dkms: old-fsf-address-in-copyright-file**
Finished running lintian.
(Reading database ... 171655 files and directories currently installed.)

Also, ls /dev/apex_0 shows nothing.

lsusb shows the device (in the uninitialized/unknown state):
Bus 002 Device 003: ID 1a6e:089a Global Unichip Corp.

Did you do something else before running the script?

Thanks in advance!

I struggled quite a bit to get frigate up and running with my camera's but that was more related to the frigate config. after running the install script everything worked fine.

I did remove the gasket-dkms before running the install script though

extract from bash history

61  sudo dkms remove gasket/1.0 --all 2>/dev/null || true
62  sudo apt remove gasket-dkms
63  sudo rm -rf /var/lib/dkms/gasket/

I use this adapter for the dual edge tpu

In frigate they are referenced as pci devices

detectors:
  coral_1:
    type: edgetpu
    device: pci:0
  coral_2:
    type: edgetpu
    device: pci:1

I assume your hardware is supported, m2 slots seem to be a bit fussy

Hi @dan-s-github thanks for the fast response. I'm using the USB Coral, which, to my understand, has less compatibility issues.

I tried running the script manually, step by step, and I get this error during the driver install when running the command `debuild -us -uc -tc -b:

Now running lintian gasket-dkms_1.0-18.4_amd64.changes ...
running with root privileges is not recommended!
E: gasket-dkms changes: bad-distribution-in-changes-file noble
W: gasket-dkms: old-fsf-address-in-copyright-file
Finished running lintian.

Do you remember seeing something like that?

[dan-s-github]

sorry, I can't help with this. this is far over my competence level regarding linux hardware.

but as this script is in regards to installing the pci drivers it might not be the compatible with usb devices

[claorden]

Oh my, I feel so embarrassed. I had issues with my usb and ended up on this thread, not realizing that this works with pci... Thanks to your comment I woke up from my nightmare and starting checking the hardware. It seems my usb cable was not ok, changed it and now everything works.

Sorry for the noise, and thanks for your comments!

I happens from time to time that we follow the wrong rabbit hole.
Glad I brought you out of the tunnel
