FG crashes on boot, FG 2020.3.16 Ubuntu 23.04

When I click the 'Fly' button in the graphic launcher FG crashes:

I do not have the Citation installed, have never touched any sound files.
What are the nasal errors?
It was working flawlessly 3 days ago, but I cannot remember if I did any updates before or after last FG boot, I have reinstalled FG

FG 2020.3.16
Ubuntu 23.04
Linux 6.2.0-20-generic

what to do? Any suggestions please?

ps: I fly with a usb yoke and an arduino controlling many switches but only half of those quoted above, not connected at the moment.

what craft are you trying to load?
if it is not the CitationX then it seems like the craft you are trying to load is using those files from the CitationX instead of copying the files to its own tree... this used to be done quite a lot in the interest of saving drive space and not having duplicate files all over the aircraft tree(s)... the problem, then, is that you have to have craft installed that you may never use...

aside from that, also check your in-sim->F10->File-Sound Configuration and be sure the proper sound device is selected... that's for the "ALC Error"...

also, you should update to the latest LTS, 2020.3.18 with 2020.3.19 waiting in the wings... there were quite a few bugs fixed between 2020.3.16 and 2020.3.18...

Code: Select all
Cannot add listener to tied property

Don't worry about these errors, they are not the problem. They're more of a warning than a critical error.

Code: Select all
XML sound: couldn't find file: 'Aircraft/CitationX/Sounds/turbine.wav'

Most likely this aircraft is using sound from the Citation? If it is, you could try installing the Citation so it can access the sound files. But I don't think this is necessarily killing the launcher. It's worth trying though.

It might help if you post the rest of the log. Maybe there is something is other clues in it.

I'm loading the excellent Twin Otter, which explains the turbine sound files.
I'll check the sound card but all was okay before...
As for FG version, it's what is proposed in the Ubuntu repository, I'll follow your suggestion to update.
