![在 Intel x64 系统上安装新内核不会写入 /var/run/reboot-required(但在 RasPi 上可以)](https://linux22.com/image/946819/%E5%9C%A8%20Intel%20x64%20%E7%B3%BB%E7%BB%9F%E4%B8%8A%E5%AE%89%E8%A3%85%E6%96%B0%E5%86%85%E6%A0%B8%E4%B8%8D%E4%BC%9A%E5%86%99%E5%85%A5%20%2Fvar%2Frun%2Freboot-required%EF%BC%88%E4%BD%86%E5%9C%A8%20RasPi%20%E4%B8%8A%E5%8F%AF%E4%BB%A5%EF%BC%89.png)
我在 Intel Atom(amd64)和 Raspberry Pi(arm64)上安装了 Ubuntu Server 22.04。
使用最新的内核更新(由 安装unattended-upgrades
),文件/var/run/reboot-required
和/var/run/reboot-required.pkgs
尚未在英特尔系统上创建(因此系统未标记为重新启动),但在 RasPi 上它可以按预期工作。

我已经读过了这个答案,但我在两个系统上都安装了该软件包update-notifier-common
。而且,符号链接/run -> /var/run
也存在。
两个系统都已从 20.04 升级,现在它在两个系统上都按预期运行。还应注意,对于其他软件包(例如libssl3
),我很确定/var/run/reboot-required
两个系统上都已更新。
这对我来说有点烦人,因为我使用这些文件,既是为了知道已安装内核更新,也是为了在指定时间触发手动重启。因此,任何关于如何解决此问题并获取要/var/run/reboot-required
写入的文件的建议都将不胜感激。
注意:我刚刚从一位朋友那里得到确认(他也有一台 Intel 服务器),这里的文件已经按预期写入。所以看起来这也不是软件包错误。

因此现在,我的解决方案是每天运行以下脚本来模仿/cron
的所需行为:apt
unattended-upgrade
#!/bin/bash
# Get last reboot time and installed kernel
lastreboot=$(date -r /home/am/last_reboot +%s)
kernelinst=$(grep 'Upgrade: linux-headers-generic' /var/log/apt/history.log -A 1 -B 1 | tail -n 3)
# Get kernel version and install date
if [[ -n "$kernelinst" ]]
then
kernelvers=$(echo "$kernelinst" | grep -oP 'linux-image-[0-9]+\.[0-9]+\.[0-9-]+[A-Z-a-z]+')
kerneldate=$(date -d $(echo "$kernelinst" | grep 'End-Date' | awk '{print $2}') +%s)
fi
# Check if reboot-required.pkgs is already updated
if [[ -f /var/run/reboot-required.pkgs ]]
then
kernelpkgs=$(grep "$kernelvers" /var/run/reboot-required.pkgs)
fi
# Write to reboot-required/reboot-required.pkgs if conditions are met
if [[ "$kerneldate" -gt "$lastreboot" ]] && [[ "$kernelvers" != "$kernelpkgs" ]]
then
# Echo to /var/run/reboot-required
echo "*** System restart required ***" | tee /var/run/reboot-required
# Echo to /var/run/reboot-required.pkgs
echo "$kernelvers" | tee -a /var/run/reboot-required.pkgs
echo "linux-base" | tee -a /var/run/reboot-required.pkgs
else
echo "Do nothing"
fi
