停用 Ubuntu 擾人的更新和升級通知

1. GUI

1. 開啟 update-manager。
2. 切到更新 update 的頁籤。
3. 停用更新通知：將 Automatically check for updates 一欄更改成 Never。
4. 停用升級通知：將 Notify me of a new Ubuntu version 一欄更改成 Never。

2. Console

2.1. 停用更新通知。

[ jonny@trusty ~ ]
$ sudo vi /etc/apt/apt.conf.d/10periodic [Enter]
#APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";

2.2. 停用升級通知。

[ jonny@trusty ~ ]
$ sudo vi /etc/update-manager/release-upgrades [Enter]

# Default behavior for the release upgrader.

[DEFAULT]
# Default prompting behavior, valid options:
#
#  never  - Never check for a new release.
#  normal - Check to see if a new release is available.  If more than one new
#           release is found, the release upgrader will attempt to upgrade to
#           the release that immediately succeeds the currently-running
#           release.
#  lts    - Check to see if a new LTS release is available.  The upgrader
#           will attempt to upgrade to the first LTS release available after
#           the currently-running one.  Note that this option should not be
#           used if the currently-running release is not itself an LTS
#           release, since in that case the upgrader won't be able to
#           determine if a newer release is available.
#Prompt=lts
Prompt=never 

最後，我們也可以移除更新管理員來永絕後患，但前提是要會先學會怎麼裝得回來還有會定期使用指令更新才行。
