aarch64报告中的"apt升级“报告”没有VM来宾在此主机上运行过时的虚拟机管理程序(qemu)二进制文件“

Question

每个apt upgrade都显示此错误/警告消息。

- Scanning processes...
Scanning candidates...
Scanning processor microcode...
Scanning linux images...

Running kernel seems to be up-to-date.

Failed to check for processor microcode upgrades.

Restarting services...
 systemctl restart udisks2.service

No containers need to be restarted.

No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.

我的系统上似乎没有安装qemu。

# dpkg -l | grep -i qemu

# find / -name "*qemu*"

如何解决/消除警告：

没有VM来宾在此主机上运行过时的虚拟机管理程序(qemu)二进制文件。

Answer 1

此输出来自被调用的程序needrestart，只是一种信息，因为“没有VM来宾正在此主机上运行过时的虚拟机管理程序(qemu)二进制文件”基本上转换为"All是最新的“。

返回“未能检查处理器微码升级”的检查不能检查CPU的微代码。可以跳过它，方法是在/etc/needrestart/conf.d/中创建一个包含$nrconf{ucodehints} = 0;内容的新的conf文件。

如果您想完全摆脱这些消息，那么您可以卸载包needrestart。但是，在进程的依赖项被更新后，将不会自动重新启动它们。
