Can you check the output of journalctl -u apache2.

#3

sure, here it is:

Please double check that you typed the command correctly, there should be output. Else:

systemctl status apache2
systemctl cat apache2
#5

ok, sorry: I included the final dot too :roll_eyes:

so…

root@DietPi:~# journalctl -u apache2

That will be it. Umm, I hope it is not a definit hardware/kernel limitation that is not working anymore with Apache2 on Bullseye. We can generate images with Lighttpd or Nginx pre-installed, if that is the case. Let me check.

EDIT: It is a limitation of the kernel:

Nothing we can do about it, as Allo never provided a newer kernel and there is no mainline support for this Actions semiconductor S500 SoC. However, we can generate a Lighttpd-based Allo GUI image.

Hang on …

thank you @MichaIng :medal_sports:

Image now up for testing. Please report back whether it boots and works well: Index of /downloads/images/testing

#9

thanks @MichaIng : AlloGUI now working :slightly_smiling_face:

though… Roon Bridge, the one and only “option” I need, is now failing

(just one image per post allowed)

#11

btw… also tried reinstalling it

dietpi-software reinstall 121

to no avail

think I’ll better go back to good 'ol “Buster”… if still available
(everything was working fine with that one, so lesson learned: if it ain’t broke, don’t fix it :roll_eyes: )

For server systems this is quite a dangerous point of view. The world around you moves and unsupported/unmaintained software gets security vulnerabilities which are abused increasingly.

How is RoonBridge failing?

journalctl -u roonbridge
tail -10 /var/log/roonbridge/*

Another feature not supported by this ancient kernel: Failed at step CAPABILITIES spawning · Issue #3582 · scylladb/scylladb · GitHub
Try this:

mkdir /etc/systemd/system/roonbridge.service.d
echo -e '[Service]\nAmbientCapabilities=' > /etc/systemd/system/roonbridge.service.d/dietpi-no-caps.conf
systemctl daemon-reload
systemctl restart roonbridge

Roon Bridge is then not able anymore to set its own nice level, but aside of a warning or so, this shouldn’t be a problem.

#17

You just printed the journal log of this exact service. Did you accidentally remove it?

ls -l /etc/systemd/system/roonbridge.service
systemctl cat roonbridge

As the directory does already exist, did you edit the service and probably broke the syntax?

cat /etc/systemd/system/roonbridge.service.d/*
#18

nope. or… if I did I’m totally unaware

all I did is… reinstalled roon bridge

ok: let me try writing a fresh image to an SD card

#19

No need, just print the output of the given commands.

EDIT: Ah, I think the Allo GUI renames the service files to disable them. Please try to re-enable it via Allo GUI, if this was the case.
