Ubuntu 25.10 - STM32CubeProgrammer upgrade fail.

[Bags]

Launched STM32CubeProgrammer v2.20.0 after a long time since last use - it prompts an update available via an icon button.

Clicked the icon, clicked Next, ticked a box, clicked "install Now", it starts download ing a big file...

When the file has finished downloading it then displays an error message - see attached screenshot.

Unable to unzip file: /home.main/.STM32CubeProgrammer/downloads//STM32CubeProgrammer2.21.0_linux64.zip

Note the double slash // in the path.

Also tried launching it direct from a terminal prompt out of my /opt folder.... same result.

Perhaps just download and install the new version manually. The update function in STM32CubeProgrammer has never been very stable.
