Error code 2 is KERN_PROTECTION_FAILURE, most likely writing to read-only memory. You should also print the faulting instruction address (scp->sc_eip) and the faulting address (sigcode). See how it's done in the error () call above. It would be easier for you to debug if you add an infinite loop after the fprintf, so the system would just hang at that point. Then you could attach GDB and inspect things. Sergey

You will notice that the line number changed. The error message used to be at line 107 and now it is at line 112. Is there a log file that I should check?

Which image did you start from? There used to be this upgrading process yes, but that dates back glibc 2.33, not glibc 2.34. Samuel

I am definitely game to help you figure out what that is, because it seems to be happening everytime I turn off this machine. It does not seem to be a massively terrible bug, but it is there. How would I go about printing that scp->sc_error value? I am running this in machine in real hardware. I get that error message after I run "sudo poweroff". I see that error message right before the Hurd gets halted. I imagine I need to turn on the kernel debugger to print that value. > >> #+BEGIN_SRC shell >> wget >> http://ftp.de.debian.org/debian/pool/main/d/debian-ports-archive-keyring/debian-ports-archive-keyring_2023.02.01_all.deb >> #+END_SRC > > Rather use https > >> #+BEGIN_SRC >> apt-get update >> apt-get dist-upgrade >> #+END_SRC >> >> The "apt-get dist-upgrade" command did fail for me. > > How did it fail? I wish I had written it down. It downloaded all the packages, then tried to update gnumach, then that failed and it said that I needed to upgrade gnumach, reboot, update libc, then upgrade the Hurd. Or something like that. It said something about hurd-dev package depending on libc, which needed to be a later version.

libdiskfs assertion failed
Hey friends! So I updated my T43 to the bleeding edge Debian in real hardware, which come on that is pretty cool! The update process was pretty easy. I will describe that in the postscript. I did get this error recently when I shutdown the Hurd: extfs: ../../libdiskfs/disk-pager.c:107: fault_handler: Assertion 'scp->sc_error = 10' failed. The above error did not seem to cause any major issues, but I just wanted to let ya'll know. Thanks, Joshua P.S. The upgrade process that I went through (it was really easy actually): I mostly copied Janneke's advice: #+BEGIN_SRC shell wget http://ftp.de.debian.org/debian/pool/main/d/debian-ports-archive-keyring/debian-ports-archive-keyring_2023.02.01_all.deb dpkg -i debian-ports-archive-keyring_2023.02.01_all.deb #+END_SRC Then I added the proper sources to my /etc/apt/sources.list deb http://deb.debian.org/debian-ports unstable main deb-src http://deb.debian.org/debian unstable main deb http://deb.debian.org/debian-ports unreleased main #+BEGIN_SRC apt-get update apt-get dist-upgrade #+END_SRC The "apt-get dist-upgrade" command did fail for me. I rebooted, and then apt told me to run "apt --fix-broken install". That actually seemed to upgrade everthing propery.. Then I ran "apt upgrade" and all my packages were upgraded. #+BEGIN_SRC shell uname -a #+END_SRC #+RESULTS: : GNU debian 0.9 GNU-Mach 1.8+git20230520-486/Hurd-0.9 i686-AT386 GNU -- Joshua Branson Sent from the Hurd on real hardware It's a T43 (1.5 GB RAM)
