(v6.24) VictronConnect - Linux AppImage crashes in Linux

AlekseyK · January 28, 2026, 7:12am

(v6.24) VictronConnect - Linux AppImage crashes in Linux. Checked in 2 versions: openSUSE TW and Ubuntu 25.10. However in Ubuntu it works longer: crashed on 1st start, now works ok, however not fully tested it yet.

Crush dump on openSUSE TW:

Based on the stack trace, the fault is occurring within libQt6Core.so.6. Since AppImages bundle their own libraries in /tmp/.mount_…, this is often due to a conflict between the bundled Qt libraries and your system’s graphics drivers or Wayland/X11 environment.

AlekseyK · January 28, 2026, 8:45am

According to the topics here it worked well with openSUSE TW on X11 previously:

The issue usually arises from issues with the various sandboxing methods and thier permissions.

Try this specific environment “strip.” It prevents the AppImage from seeing your system’s desktop themes, which is the #1 cause of this specific Qt6 crash on Tumbleweed.

env -u QT_QPA_PLATFORMTHEME ./VictronConnect-x86_64.AppImage --no-sandbox

AlekseyK · January 28, 2026, 10:54am

Hmm, now works fine after reboot without any changes to the environment. May be some kernel upgrade or something. Will look more however.

P.S. 2nd run - crash immediately. Log attached:

VictronConnect.log (2,2 КБ)

This does not work - crashes immediately as well.

bachete · January 28, 2026, 11:52am

So the reboot didn’t work?

I run that on fedora with gnome, no issues whatsoever.

AlekseyK · January 28, 2026, 12:21pm

Yes, run successfully only once, now crashes on every start in openSUSE TW. Ubuntu version can’t connect to the device and even do not ask for a PIN which I had changed in mobile app BTW.

AlekseyK · January 28, 2026, 12:36pm

I have the latest suse TW. Bluez is installed on both Ubuntu and Suse.

bachete · January 28, 2026, 12:44pm

Yeah the bluez thing is a kernel bug that was fixed like 10 years ago,but was somehow reintroduced.

Me filing a bug report didn’t help any, haven’t heard back from the bluez Devs on that. Perhaps it’s already upstream, no way to know.

I can’t really tell you from here what the issue is. Other than what I saw.

Kerberos · February 5, 2026, 7:44pm

I do have the same problem as documented here

In the Manjaro community someone provided an older version (5.10.x) which is working. But that’s an older major release.

Apart from that other cases are documented here in this forum as well. Seem to be a general problem with newer versions.

As it’s an app image Victron has to do something about it. Extracting the App Image and get it running won’t work either.

bachete · February 5, 2026, 10:12pm

While generally Id agree, Id tend to lean towards the system settings and sand boxing as the likely candidate for your issue.

Would you please try running the app thru the terminal to see if the issue is stated there:

./VictronConnect-xxx_xx-xx.xx.AppImage

Or perhaps trying to locate the:

VictronConnect.log

If these are unsuccessful perhaps try:

coredumpctl info VictronConnect

Without any really log output, we wont be able to diagnose the issue.

If all else fails and you feel like the issue is with some core part of the app image you can use the following appended option to have a gander inside.

--appimage-extract

Thanks

AlekseyK · February 6, 2026, 2:26pm

I’d put my VictronConnect.log above, can do it again: VictronConnect.log (2,2 КБ)

coredumpctl info VictronConnect outputs the same dump as in my 1st post.

--appimage-extract output:

Which interface are you trying to connect?

This implies an issue with the network manager, and while guessing at what the actual issue is:

sudo journalctl -u bluetooth -f

Would help us point to a more exact error.

If its what I think it is:

sudo dmesg -w | grep -i bluetooth

Will help us pinpoint the suspected issue.

Me?! It your application tries to connect something. I have wired Ethernet connection.

I have no problems with the network manager - it works fine.

I cant see a connection attempt by victronconnect

Have you tried using the no sandbox option ? I asked you already about that, I remember.

./VictronConnect.AppImage --u-rules --no-sandbox

I still suspect that the sandbox is not allowing victron to load its special bluetooth package.

In the ubuntu dmesg we see :

$ sudo dmesg -w | grep -i bluetooth
[201981.955551] traps: bluetoothd[30876] general protection fault ip:64ca6689ea33 sp:7ffd61b486f0 error:0 in bluetoothd[45a33,64ca6687d000+108000]

That looks like a bug in the bluetooth driver

AlekseyK · February 6, 2026, 4:15pm

It is on Ubuntu, no such error in SUSE: it just crashes on start.

Sorry, no connection attempt as we have no electricity now. On SUSE it crashes before any attempts. Will try without sandbox when power is on again, however as I remember it did not help me previously

This implies an issue with the network manager, and while guessing at what the actual issue is:

I get that as well, but VC works for me, on Debian 13

VictronConnect.log (2.9 KB)

It hangs for a good 30s on Bluez during startup of the program, but i dont have a bluetooth adapter in my PC, so i never worried about that

bachete · February 6, 2026, 4:33pm

yes, we tried with a specific option, I thought maybe it was QT environment conflict.

We should try with just the no sandbox to see if it actually produces a connection attempt.
