树莓派新烧写了ubuntu22.04的版本，新版本需要安装更新一些软件，发现只要一更新，就报错：

Processing triggers for man-db (2.9.4-2) ...
Scanning processes...
Scanning processor microcode...
Scanning linux images...
Running kernel seems to be up-to-date.

Failed to check for processor microcode upgrades.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

解决这个问题，需要修改树莓派的配置文件：

sudo vim /etc/needrestart/needrestart.conf

 将

#$nrconf{ucodehints} = 0;

改为：

$nrconf{ucodehints} = 0;

保存退出，再安装软件试试，问题解决。

或者执行：

sudo apt-get purge needrestart

也可以将问题解决。
