我正在运行标准的 Ubuntu 18.04。
$lsb_release -a
LSB Version: core-9.20170808ubuntu1-noarch:security-9.20170808ubuntu1-noarch
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic
但我缺少超线程....它在 BIOS 中 100% 启用。我禁用并启用它只是为了检查问题是否存在,但事实并非如此...然而 cpuinfo 说:核心:4,兄弟:4,而应该是兄弟:8...
我不记得我的桌面上什么时候发生过这种情况......可能是从 16.04 升级到 18.04 之后。
我正在粘贴lscpu
。

我尝试按照mokutil
建议禁用安全启动,结果得到了
$sudo mokutil --disable-validation
EFI variables are not supported on this system
所以我检查了安装lsblk
$lsblk

您必须在 EFI BIOS 中禁用安全启动。
