Hello user,

I would like to use under Kali OpenVAS and installed Kali on USB, in VirtualBox and native on a computer. The result for all 3 installations is identical. I cannot make any changes in the "Settings". There is always the same error when saving:

"Given time_format was invalid"

The edition of "sudo gvm-check-setup" does not result in anything striking:

It seems like your GVM-23.11.0 installation is OK.

The scan in OpenVAS works. But I would like to set the time zone "Berlin" and use "German" as a browser language. Unfortunately, none of this works.

Does anyone have an idea where the problem is and how I can solve it?

Please info.

Thanks Thomas
