Installation Error on Latest Version of RaspberryPiOS

[Dewey3]

While doing an update and upgrade to one of my 8GB RPi 4's last week, the attempted upgrade kept erroring out. Doing a little GoogleFoo, I saw somewhere where the RPi OS was breaking when upgrading (the new kernal is Linux kernel 6.6.20 - 6f16847710cc0502450788b9f12f0a14d3429668). So this week, I downloaded the latest RaspberryPiOS, dated 3/15/2024, and started fresh. Now, when going through the "Add all of the libraries needed" portion of the TR install, it keeps ending with:

Errors were encountered while processing:
 xtrx-dkms
E: Sub-process /usr/bin/dpkg returned an error code (1)

I went back through the installation and found were the error is occurring. This is what I am seeing:

Building for 6.6.20+rpt-rpi-v8
Building initial module for 6.6.20+rpt-rpi-v8
Error! Bad return status for module build on kernel: 6.6.20+rpt-rpi-v8 (aarch64)
Consult /var/lib/dkms/xtrx/0.0.1+git20190320.5ae3a3e-3.2/build/make.log for more information.
dpkg: error processing package xtrx-dkms (--configure):
 installed xtrx-dkms package post-installation script subprocess returned error exit status 10

I looked for the make.log referenced in the error, but the /var/lib/dkms... directory stops after the ...-3.2. There is no /build/ directory nor make.log there. Does anyone know if this is going to be a problem. While I have not yet run TR, the "Build" process did complete without any errors.

Update: I rebooted and just performed another update and upgrade. I am now getting errors similar to the errors that I got when I first tried to update before grabbing the latest RaspberryPiOS. I already knew that the errors were a RPiOS induced error during the TR installation and not TR itself, but just wanted to know if it would cause a TR problem. If anyone is interested, this is the error:

Hopefully the last update: after more GoogleFoo, I got the idea to uninstall dkms since I was running some tests and had nothing to lose. So I completely removed and purged dkms then did another update and upgrade and lo and behold, no update errors. I then reinstalled dkms and did a final update and upgrade and everything appears, and hopefully stays well. If time allows, I will start the TR installation over tomorrow from a fresh RPiOS, but doing the uninstall then reinstall of dkms and will see how that works. BTW ... TR did work without any apparent problems despite the error report during the install.

Ok, here is what I've come up with. Being an intermediate Linux user, my way of trying to troubleshoot and solve this was through process of elimination. First, I did discover that something in the "Add all of the libraries needed" portion is what causes dkms and xtrx-dkms to be installed. The problem is that something is broken in the way xtrx-dkms works with the latest release of RPiOS resulting in constant errors when installing packages.

So on a brand new RPiOS installation (each time I would perform an elimination), I continually checked for the presence of dkms and xtrx-dkms which did not show up until after completing the "Add all of the libraries needed" portion of the installation. I first tried uninstalling xtrx-dkms and dkms but attempting that threw errors every time I tried to reinstall xtrx-dkms. So my solution was to just uninstall and reinstall dkms only. After doing so, then re-running the "Add all of the libraries needed" step, I did not receive any errors for the remainder of the installation.

So with all that said, the bottom line is that it is something that breaks when xtrx-dkms is installed on the latest RPiOS, which in turn throws errors with most (if not all) package installations and upgrades after that. I did find that TR worked whether I ignored the error during TR installation, or used the dkms uninstall-reinstall that I mentioned above. What I like about the dkms uninstall-reinstall method is that I do not constantly get errors when performing an 'update or upgrade or installing anything else afterwards. I apologize for the way I had to go through this, then explain it here but as I said, I am only an intermediate Linux user.

@Dewey3 ... what command did you use to determine if xtrx-dkms and dkms were installed? Also, what was the uninstall command you used?
