更新固件bug ubuntu LIVE

从带有Ubuntu iso的CD或USB启动以重新安装所有内容时,会出现错误

[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later) 

我按照建议安装了intel-microcodes并重新启动

 sudo apt-get install intel-microcode intel-microcode is already the newest version (3.20180425.1~ubuntu0.17.10.1). 0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded. 

重启后,仍然存在错误……

我能做什么?
