deb http://extras.ubuntu.com/ubuntu precise main
deb-src http://extras.ubuntu.com/ubuntu precise main

1. 暫時 把 http://extras.ubuntu.com/ubuntu/ 排除在 軟體來源

2. 方法
先安裝 gksu 套件
gksudo gedit /etc/apt/sources.list
最下方這兩行
deb http://extras.ubuntu.com/ubuntu precise main
deb-src http://extras.ubuntu.com/ubuntu precise main
改成
# deb http://extras.ubuntu.com/ubuntu precise main
# deb-src http://extras.ubuntu.com/ubuntu precise main
儲存
然後
sudo apt-get update

3. 過一段時間 有需要 再把 # 移除

這一篇 說明已經解決了這個 Bug
方法 見下面的 網頁
1-1. https://github.com/openstack/nova/commi ... domains.py
錯誤原因是
原來的 dns_domains table 是以 latin1 編碼
應該改為 utf-8 編碼
見第 70 行
mysql_charset='utf8',
1-2. 找看看 你的 ./nova/db/sqlalchemy/migrate_repo/versions/ 目錄下 有沒有 096_recreate_dns_domains.py 檔案
nova/db/sqlalchemy/migrate_repo/versions/096_recreate_dns_domains.py
如果有 參考
https://github.com/openstack/nova/commi ... domains.py
的內容 修改對應文字內容

2. 如果還有錯誤訊息 請全部複製 貼上來

到082就没了

我在这个目录下/usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/找到了这个文件fix_dns_domains.py，内容跟recreate_dns_domains.py有很多相同的，但里面是mysql_charset='utf8
