@gene, you can probably set the locale to your environment by typing: sudo

ISTR doing that at first boot, but did locales again anyway, set
everything to en-UTF8.
sudo apt update still finishes up with:
All packages are up to date.

Can you post yours? I've looked at mine but don't see anything obvious.
Thanks a bunch.

You could try this image that contains preempt_rt for the Pi 5 (Linuxcnc

I don't have a Pi5 to test it but others say it worked.
This is an updated image from our Raspberry Pi 4 one that is built for
the newer Pi 5 CPU
sudo apt upgrade should update to 2.9.2
I tried that with my rpi4 that is running your image, but I get this:

I say its installed, I've done the install twice, but here is an ls -l of:

which has no sign of that key, so where did the installer put it?
That key 3CB9FD148F374FEF has been installed, twice. But I can't find it.
uname -a sys:
Linux rpi4.coyote.den 6.1.54-rt15 #1 SMP PREEMPT_RT Wed Sep 20 20:36:44
AEST 2023 aarch64 GNU/Linux
Its latency-test is not as good as my old 4.19 something build but its
plenty good enough to move my lathe nicely.
But from the message, I found it in /usr/share/keyrings and put a copy
in trusted* and now its offering me 19 updates. Which were all security
related from debian but locale complained:
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
How to fix that? I don't have an /etc/locale but I do have these:
-rw-r--r-- 1 root root 2996 Jul 13 14:07 locale.alias
-rw-r--r-- 1 root root 9431 Oct 17 04:24 locale.gen
but it recommends I run locale-gen, which returns very quickly w/o
errors and does not generate anything in the locale directory, so I'll
delete the directory I made. Done.
And after all this I'm still bumfuzzled. And can't update linuxcnc.
Thanks & Happy New Year All.

My RPi5 arrived over Xmas and I just fired it up, was offered to
install LinuxCNC directly from what we offer in Debian, and then ran
latency tests. Graphics (as in video but also the extra art from your X
interface when ALT-tabbing through your applications) have the most
effect
on the latency. I/O from the SD does not seem to affect it too much.
The numbers you show are _awful_ though?
It doesn't look like the LinuxCNC installation has installed the
correct kernel. (I seem to recall that I had to do a fair bit of
fiddling to make it happen, it's a Pi thing)
Rebooted with
Linux version 6.1.0-rpi7-rpi-2712 (debian-ker...@lists.debian.org)
(gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian)
2.40)
#1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24)
but do not see any relevant change.
That's the wrong kernel: "PREEMPT" is not enough, you need "PREEMPT_RT"
in the uname string.
This is usually the difficult part of getting systems with out-of-tree
vendor-specific kernels to work well with LinuxCNC.
