Ubuntu Desktop 22.04 禁用自动更新

Ubuntu 的自动更新并不稳定，之前的一次推送更新了内核版本，稳定性影响比较大，禁用自动更新的方法如下：
1.在设置里禁用软件更新

2.关闭 unattended-upgrades

如果只禁用上面的更新，unattended-upgrades 还是会在后台更新软件包，也需要禁止。

# unattended-upgrades 更新的内容可以在 /var/log/apt/history.log 里查看
systemctl status unattended-upgrades

# 禁用自动更新
systemctl disable unattended-upgrades

禁用后查看结果如下，后续再查看 /var/log/apt/history.log 就不会有软件自动更新的日志了。

输入systemctl status unattended-upgrades

 unattended-upgrades.service
     Loaded: masked (Reason: Unit unattended-upgrades.service is masked.)
     Active: inactive (dead)
