Nagstamon 3.14 not starting since Plasma 6 #1015

timodenissen · 2024-03-11T11:26:02Z

Using Arch Linux with the most recent Plasma 6 update, Nagstamon 3.14 no longer starts.

Cleaning my configuration to make sure it's not a profile problem:

cd ~
mv .nagstamon{,_orig}

Starting Nagstamon from Konsole via nagstamon crashes:

QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout
QThread: Destroyed while thread is still running
zsh: IOT instruction (core dumped)  nagstamon

Running from bash results in:

QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout
QThread: Destroyed while thread is still running
Aborted (core dumped)

ps auxf | grep -i "nagstamon" shows no Nagstamon process is running.

Prior the Plasma 6 update (with Plasma 5.27) everything worked just fine.

The text was updated successfully, but these errors were encountered:

Hi @timodenissen, how bad. Actually Nagstamon supports Qt6, which Plasma 6 is based on too. So this is really strange. I will try to reproduce by setting up an Arch instance.

HenriWahl · 2024-03-14T15:22:12Z

Hi @timodenissen - do you know of an fast way to get an Arch Linux up and running? I did not expect to come out in a shell for installing. Don't get me wrong, I ❤️ shells, but looks more tenacious than assumed.

HenriWahl · 2024-03-14T15:54:21Z

@timodenissen another question: do you use Wayland or Xorg?

HenriWahl · 2024-03-14T22:05:04Z

@timodenissen how did you install Nagstamon?

timodenissen · 2024-03-15T06:26:21Z

@HenriWahl The fastest way could be using archinstall.

I use the Plasma wayland session, with Plasma 5.27 this was not an issue.

I installed Nagstamon via the AUR package. A clone of the repository also results in the same errros.

+1 to the issue, after recent system upgrade Nagstamon won't load anymore. I also noticed that trying to run nagstamon via pdb-clone, I can get it to work but without any UI whatsover - I hear the sound of alerts, can see the process running, but UI appears for a fraction of a second and immediately crashes.

Not sure how helpful it will be for debugging, but will leave the outputs, in ~/.nagstamon/nagstamon.conf I enabled debug mode:

...
debug_mode = True

HenriWahl · 2024-03-18T21:50:44Z

@timodenissen thanks for the hint with archinstall. The downside is that I only receive a black screen after logging in into Plasma desktop inside a VM.

What is your desktop session manager? I choose the default sddm (or something like that) with Wayland.

Edit: Now I used X11 instead of Wayland and now I get a KDE desktop after logging in.

timodenissen · 2024-03-20T08:58:01Z

I use SDDM with no special configuration. Please be aware that X11 is no longer supported by Plasma 6 and may falsify reproducing the error.

HenriWahl · 2024-03-20T09:11:24Z

Yes, I think checking it with Wayland is definitely more useful. I will try to get it running.

HenriWahl · 2024-03-22T19:57:39Z

At least got Wayland session of Plasma6 running in VM. Now the next questions as non-Arch-user: where did you install Nagstamon from?

Edit: Found it.

Edit 2: I can confirm the immediate crash.

HenriWahl · 2024-03-22T20:56:15Z

@timodenissen this are my findings:

Nagstamon crashes in Wayland and X11 - so the windows systems seems to be innocent
Nagstamon runs from source in a virtualenv environment with Qt6 installed by pip

I assume that the Qt6 version in Arch causes the trouble somehow, because the crash happens as soon GUI is involved.

Via journalctl I get this crash message:

HenriWahl · 2024-03-22T21:07:02Z

@timodenissen the mention of libpulse inspired me to try to disable sound.
I started from source in virtualenv environment where it does not crash and disabled sound.
Back with normal nagstamon start it does at least not crash now at the beginning. So I am almost convinced something with ArchLinux Qt6 + sound (libpulse?) is wrong, Maybe some package is missing and should also be listed as dependency?

HenriWahl · 2024-03-22T21:15:17Z

@timodenissen well, I installed the not yet installed package pulseaudio-qt and now there is no crash. Can you reproduce this?

bouzouste · 2024-03-28T11:49:21Z

@HenriWahl , @timodenissen I am sorry for stepping in. I personally use Endeavour OS (arch based) which also seems to have an issue with nagstamon after updating to Plasma 6. I also have the PulseAudio-qt package installed and I still see core dumps. However, in my case, nagstamon somehow seems to be working if it is not set to display a floating status bar but rather shows an icon in systray

timodenissen · 2024-04-02T06:45:21Z

@HenriWahl Sorry for the late reply, I was on vacation.

That's interesting, my sound server is pipewire:

pactl info | grep "Server Name"
Server Name: PulseAudio (on PipeWire 1.0.4)

I could try switching back to PulseAudio and see if that would solve the issue, but that has to wait until tonight.

@bouzouste Thanks for the hint :) Unfortunately the crash also occurs with a complete new and empty Nagstamon profile =/

bouzouste · 2024-04-03T02:06:06Z

@timodenissen I confirm that the app crashes even when there is no configuration. However, If you already have a conf file, you could try changing the following two lines:

statusbar_floating = False
icon_in_systray = True

so that the floating status bar is disabled, and it (probably) won't crash.

If on the other hand, you don't have any configuration available, then you could try using an older version of nagstamon (3.8.0 or older) which seems to be working without issues (versions 3.8.1+ to 3.14+ seem to not like plasma 6)

timodenissen · 2024-04-03T06:18:06Z

@bouzouste Thanks, now Nagstamon's not crashing but shows me a flashing tray icon (expected) but unfortunately I need the window =/ I wait for @HenriWahl to check and add a fix (not that much of a coder myself) or wait for the flatpak to update to latest stable (currently 3.6.0, which somehow can't work with our Prometheus Alert Manager).

In the meantime I check the Nagios and Prometheus Alert Manager with their respective web interfaces.

HenriWahl · 2024-04-03T06:34:53Z

@timodenissen strange thing that the window isn't working. Well, maybe you could test the 3.14 flatpak release currently being in development at flathub/de.ifw_dresden.nagstamon#8

HenriWahl · 2024-04-28T20:27:52Z

https://flathub.org/apps/de.nagstamon.nagstamon is finally out.

gaestur · 2024-04-29T05:25:56Z

Fedora 40, Plasma 6. Neither 3.14 from flathub (de.nagstamon.nagstamon), nor 3.14 (or 3.15 from the "latest" repo) RPMs work.
Here's an output (it is +/- similar in all cases)

This is after manually permitting flatpak access to system and session buses. Without it (by default) it additionally gives multiple errors like this:
kf.solid.backends.udisks2: Failed enumerating UDisks2 objects: "org.freedesktop.DBus.Error.Disconnected" "Not connected to D-Bus server"

timodenissen · 2024-04-29T06:58:27Z

Even after updating to Python 3.12, Nagstamon 3.14 won't show the GUI, neither does using the flatpak de.ifw_dresden.nagstamon.

HenriWahl · 2024-05-02T18:58:24Z

@timodenissen please try the new flatpak de.nagstamon.nagstamon

HenriWahl · 2024-05-02T19:03:02Z

@bbhtt do you think the permissions should be increased?

richarson · 2024-05-02T20:57:54Z

@HenriWahl same behaviour for me with the latest flatpak as with running from the tar.gz, the UI flashes and immediately closes.

@bbhtt do you think the permissions should be increased?

It does not need system or session bus. You need to figure out which bus name it tries to connect to by running it with flatpak run --log-session-bus <appid> and dbus-monitor etc.

timodenissen · 2024-05-03T06:40:14Z

I did a quick test with the latest main branch:

cd /tmp
git clone https://github.com/HenriWahl/Nagstamon.git
cd Nagstamon
python ./setup.py build
python ./build/scripts-3.12/nagstamon.py

results in

QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout
QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout
QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout
QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout
QLayout: Attempting to add QLayout "" to StatusWindow "", which already has a layout

Same error - the status window doesn't open.

When stopping Nagstamon.py from the systray via the context menu quits the process, using Ctrl+C results in:

Traceback (most recent call last):
  File "/usr/lib/python3.12/site-packages/Nagstamon/QUI/__init__.py", line 2553, in reset
    @Slot()

KeyboardInterrupt
zsh: IOT instruction (core dumped)  python ./build/scripts-3.12/nagstamon.py

Running the latest flatpak de.nagstamon.nagstamon still doesn't work.

HenriWahl · 2024-05-04T21:56:46Z

At least I can confirm that the flatpak does not run on a fresh Fedora 40 Plasma install.

I tried to run it from source on Fedora 40 Plasma and there it runs with Python 3.12.3 and Qt 6.7.0. Qt6 is missing some multimedia backend:

Maybe this leads to a solution, I will check later.

timodenissen · 2024-05-15T06:29:53Z

With some recent QT updates, I now get these new messages:

Does it run? And in which context did you get this updates? On your Linux system or in virtualenv?

Okay now this is strange... I have no new Arch updates installed since yesterday and wanted to dive deepter into debugging. I installed Nagstamon via flatpak in an Ubuntu 24.04 VM and it worked, went back to Arch and... now it's working.

After cloning this repository to /tmp and starting nagstamon.py from the just very checked out repository I was presented with the "Create new configuration" dialog window. My configuration is gone but at least I can work with Nagstamon again.

Running Nagstamon via the AUR package works as intended again.

For me this issue is resolved.

richarson · 2024-05-28T21:27:13Z

I still can't run nagstamon, either from flatpak or from git, under X11 or Wayland.

Under Wayland from git I get additional errors, maybe due to Fedora's python version (3.12.3)?:

$ ./nagstamon.py

richarson · 2024-05-28T21:31:01Z

OK, those additional errors are fixed/silenced with this Arch fix:

sed -i Nagstamon/QUI/qt.py -e "s/QT_VERSION_STR.split('.')/QT_VERSION_STR.split('.')[0:3]/"

Still, nagstamon is not working for me :(

Really strange, nice to hear it is solved for you.
