Hello,
I've installed the last release of MATLAB ( 2019a ).
Everything seems to be OK but when I launch matlab I have :
MATLAB is selecting SOFTWARE OPENGL rendering.
/usr/bin/python3: symbol lookup error: /usr/bin/python3: undefined symbol: XML_SetHashSalt
When I close MATLAB , I have :
Exception in thread "Thread-11": java.lang.NullPointerException

at com.teamdev.jxbrowser.chromium.internal.ipc.IPC.b(Unknown Source)

at com.teamdev.jxbrowser.chromium.internal.ipc.b.run(Unknown Source)
at java.lang.Thread.run(Thread.java:748)
Do you have any idea about those issue?
I forgot to add:
Linux debian stretch kernel 4.9.0.8
Thank you for your support.

Fot the first error , I only add a LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libexpat.so before launching matlab

In Linux Debian Stretch is libexpat located at /lib/x86_64-linux-gnu/... not in /usr/lib/x86_64-linux-gnu/... !
Could anybody confirm, that this solution is functional?

In my case /usr/lib/x86_64-linux-gnu/libexpat.so is a link to /lib/x86_64-linux-gnu/libexpat.so.1.6.2
and it works very well

Dear all,
I experience the same kind of problems with R2019a on Linux Ubuntu 18.04
See details below.
Is there any update on this topic ?
best regards,
François.
When I try the figure properties editor (I don't like the new one by the way) I get in matlab window line :
