Keyboard layout not recognized (Ubuntu 20.04.3 LTS)

I've bought this TECKNET keyboard:

Unfortunately, Ubuntu 20.04.3 does not automatically recognize the different layout, so that, for example, if I click "U" key, it gives "4"; in practice, all keys with FN values overlap the white ones, without pressing FN at all. In other threats I've read that I may use xev command to manually configure the new keyboard. However, is there a faster way?

Solution 1:

Ubuntu never recognizes a keyboard layout. You always need to select the matching layout yourself, either during installation, or afterwards, in "Settings", "Keyboard", "Input sources".

The Ubuntu installer includes a tool that allows it to guess the keyboard layout based on some keys you type. Unfortunatelly, I am not aware of such tool that could be run in a regular Ubuntu install.
