STM32CubeMonitor v1.4.0 not acquiring on Ubuntu 20.04

[MGieb.1]

I was using STM32CubeMonitor v1.30 on Ubuntu 20.04 without any problems.

After upgrading to v1.4.0 my previously working flows no longer capture any data.

My ST-Link V3 probe shows green on the "acq in" and "aqc out" nodes..

When I click on Start Acquisition, my variable names show in the charts and gauges, but no data.

I downgraded back to v1.3.0 and the Exact same flow works in v1.3.0.

If I launch v1.4.0 from the command line, I see some warnings and an error.

Is this a hint as to why acquiring data doesn't work?

Hello @MGieb.1​ 

Could not reproduce your issue on my Ubuntu 20.04, I get the same sandbox_linux.cc error but no dbind-WARNING. May be this post : https://unix.stackexchange.com/questions/532585/getting-dbind-warnings-about-registering-with-the-accessibility-bus may help?

If possible, can you share your flow in private , in order I try it on my machine.

Hello Richard,
Thanks for reaching out.
Yes, I can share the flow with you.
Not sure if replying to this email thread is private or will it end up in the forum?

Hello @Richard.Chvr

I tried the suggestion for the dbind-WARNING of setting:

export NO_AT_BRIDGE=1 

The warning went away in v1.4.0 but it did not fix the problem of no data acquiring.

Hi,

Root cause of the issue have been found, will be corrected in next official release 1.5.0.

Sounds great! I'll definitely try it out when it's available.
