Package in stable repo are failing on Ubuntu 22.04+

[drikster80]

The installation of the gasket-dkms has begun failing on Ubuntu. It looks like the problem was solved 4 months ago in this patch, but the official Google Repos seem to be abandoned.

REPO: https://packages.cloud.google.com/apt/dists/coral-edgetpu-stable/main

It's a bit embarrassing that an official google repo for a google product seems to be abandoned when it's called "stable". :-(

Does anyone know of a supported Debian repo at this point?

[robertzaage]

@mbrooksx Are you able to keep these repos in sync? 😊

Chiming in to say I am having the same issue after applying apt update && apt upgrade and now a previously working TPU is no longer available

mokutil --sb-state
SecureBoot disabled

dpkg -l | grep gasket
ii  gasket-dkms 1.0-18 all DKMS source for the gasket driver

lspci -nn | grep 089a
01:00.0 System peripheral [0880]: Global Unichip Corp. Coral Edge TPU [1ac1:089a]

I like to +1 this. My Frigate NVR instance with a Google Coral TPU chip broke after running apt update/upgrade on ubuntu 23.04.3 Desktop.

My workaround was to reinstall the OS to Ubuntu Server 23.03 (It's on Linux Kernel 5.XX)

Here's an issue in the Frigate repo to help others have breadcrumbs LINK

Same problem here. Reverted to CPU detection as TPU unusable. Reinstalling in my case seems to be too complicated and risky.
How to build the correct package for kernel 6.5??

[noisyscott]

@Mikescotland, @Leon-Sam

You can solve this issue by building then installing the DKMS driver as outlined on the project Readme https://github.com/google/gasket-driver

[Leon-Sam]

I just reinstalled the OS to Ubuntu server 23.04 which has a major kernel < 6. The entire server was configured via an ansible script, and didn't feel like building the gasket driver as apart of the script or keeping track of the artifact else where.

But I appreciate the help! @noisyscott

Has anyone successfully built and run for Ubuntu 23.10 on 6.5.0-15?

Build succeeds, but modules won't load due to mismatch

sudo insmod /lib/modules/6.5.0-15-generic/updates/dkms/apex.ko.zst
insmod: ERROR: could not insert module /lib/modules/6.5.0-15-generic/updates/dkms/apex.ko.zst: Invalid module format

sudo dmesg
[ 2091.374207] module apex: .gnu.linkonce.this_module section size must match the kernel's built struct module size at run time

I tried messing with build options etc as lintian complained about bad distribution, but removing that didn't help.

@izzeho Did you built the module from this repo against the exact mentioned kernel? Are you signing your module afterwards (secure boot)?

I believe so, running on the build machine using commands from repo. Vermagic above gives correct kernel. Secure boot is off.

$ mokutil --sb-state SecureBoot disabled

[Szewcson]

Will the repo be updated in the future?
