[LJB]

Hi. Newby question about my STM32CubeMX (6.14.0) installation on Ubuntu. With the initial 'update', why do I get so many...

...messages on the console? Is this normal? Its being going on for hours now !!!!
(I have a good fiber connection to the internet)

Thanks for your time

Followed step described in the readme as close as possible:

On Linux®:

• On STM32CubeMX-Lin line, click "Get software" to download the package.
• Extract (unzip) the downloaded package.
• Make sure you have administrator rights to access the target installation directory. You can run the installation as root (or sudo) to install STM32CubeMX in shared directories.
• Do chmod 777 SetupSTM32CubeMX-6.14.0 to change the properties, so that the file is executable.
• Double-click on the SetupSTM32CubeMX-6.14.0 file, or launch it from the console window.

I did not do the last step but instead started the app with:
$ sudo /usr/local/STMicroelectronics/STM32Cube/STM32CubeMX/STM32CubeMX

I am not a Cube user...

For several reason, I would avoid running normal user space applications as root.
They should never require such privileges.

Installation is a different matter.

Especially considering the frequent hick-ups and issues on this forum (especially with logging in), this might be a problem on the other side - at ST.
Or poor design that can't deal with well with networking latencies.

Apart from that, I don't trust any application which regularly phones home at runtime, for no apparent reason.
Or an IDE with "web-apps" which could be done equally well or better locally.

And on a side note ...

> Do chmod 777 SetupSTM32CubeMX-6.14.0 to change the properties, so that the file is executable.

From the readme file, I suppose. This is bad style, as it grants blanket right to everybody.
I would do chmod +x <file> instead.

Yes, I had the same concerns, but doing the correct way do not solve this problem. Sigh.

As you can see, these messages have "Info" level. So no need to really be concerned.

And, I would not start a GUI application from a shell, unless you really want to see those messages, e.g. if the application crashes or fails to start up.

Create a desktop launcher or start menu entry, and run it that way.
Although I think the Cube installer should have done that already.
But this way, you are not bothered with a torrent of info messages.
