Some users seems to have some problems with Netdata. Note sure if is just related to DietPi or Debian
Torben
Natdata is installed from Debian repository. It’s simply an apt install netdata we do. No magic, no config. So I guess issue is with Debian in general.
As already stated on the Roon forum, the package is missing on Debian side.
root@DietPi5:~# apt install netdata
Package netdata is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
Error: Package 'netdata' has no installation candidate
root@DietPi5:~#
If Netdata has been installed via DietPi software repository, Trixie upgrade is already blocked

Thanks @Joulinar
Just installed Trixie (script):
“trixie”
Linux DietPi 6.12.41+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.41-1 (2025-08-12) x86_64 GNU/Linux
Did not have any problems with the installation. And so far everything works just fine
I updated 2 Raspberry, and the script worked fine. Had many dpkg warning about not empty folders…
The only issue are the missing signature in the apt sources.
Why is that missing?
Might be for Raspberry Pi SBC running for years, key package needs to be updated Debian Trixie | Testing and migration script · Issue #7644 · MichaIng/DietPi · GitHub
THX 
Is there a way to test “signature” on an installation?
Have a nice WE
We are currently checking whether we can integrate the key package update for RPi device.

How can i solve the warning for the unifi repo?
All packages are up to date.
Warning: https://www.ui.com/downloads/unifi/debian/dists/stable/InRelease: Policy will reject signature within a year, see --audit for details
Audit: https://www.ui.com/downloads/unifi/debian/dists/stable/InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is:
Signing key on 4A228B2D358A5094178285BE06E85760C0A52C50 is not bound:
No binding signature at time 2025-07-31T14:19:58Z
because: Policy rejected non-revocation signature (PositiveCertification) requiring second pre-image resistance
because: SHA1 is not considered secure since 2026-02-01T00:00:00Z
This has nothing to do with the RPi package. It’s a 3rd party package source you added manually yourself. Check the Unifi docs. But actually it seems a warning only, not an error.
Before update to Trixie I did not have any error. Now it shows:
root@DietPi:~# dmesg -l 0,1,2,3

What about sharing some more information on the device used?

sorry for my ignorance but, I’ve upgraded and not sure this is correct:
root@homeassistant:~# echo “$G_DISTRO_NAME”
“trixie”
root@homeassistant:~# uname -a
Linux homeassistant 6.12.47+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.12.47-1+rpt1 (2025-09-16) aarch64 GNU/Linux
…shouldn’t Debian be showing 13 (not 12)?
Kernel version has nothing to do with Debian version
agh, thanks.
…and thanks for your quick repose!
What is the ‘best/right’ way of identifying my Debian version (as it doesn’t show in the headers when connecting to my PI)?
edit: By header, I mean the following:
Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.
