Before fixing the error, you must understand its anatomy:

dmiedit may be an older or vendor-specific tool. Standard Linux tools (e.g., dmidecode ) don’t write DMI. You might need Dell’s smbios-utils or system-dmiedit (part of freedekit or vendor kits).

The error can be traced to one or more of the following six root causes:

dmiedit /u /handle=0000 /i dmi_data.txt
