See upstream in https://midnight-commander.org/ticket/3254 :
``` on the console it's the kbd package that's broken because half of the keymaps are shifted by 2 compared to the other half. To make it worse, the kernel's builtin table just doesn't match the standard "us" layout shipped by kbd or console-tools or whatever that's called nowadays. … Until that one is solved (i.e. the kbd/console-tools package ships keymaps that are consistent with each other and with the kernel's default) there's nothing mc could do. ```
