[Ubuntu] (修訂) 快速移轉 Ubuntu 環境（套件及個人資料）

重新思考了一下後，做了如下的修正：
--------------------------------------------------------------------------------------------------------------------

備份目前電腦上的套件列表及 keys、家目錄

• mkdir /media/usb/backup_all_settings
• dpkg --get-selections > /media/usb/backup_all_settings/Package.list
• sudo cp /etc/apt/sources.list /media/usb/backup_all_settings/sources.list
• sudo cp -r /etc/apt/sources.list.d/ /media/usb/backup_all_settings/sources.list
• sudo apt-key exportall > /media/usb/backup_all_settings/Repo.keys
• sudo chown -R `whoami` /media/usb/backup_all_settings
• rsync -r --progress /home/`whoami` /media/usb/backup_user_home

至新電腦上還原及匯入套件、keys

• rsync --progress /media/usb/backup_user_home /home/`whoami`
• sudo apt-key add /media/usb/backup_all_settings/Repo.keys
• sudo cp /media/usb/backup_all_settings/sources.list /etc/apt/sources.list 
• sudo apt-get update 
• sudo apt-get install dselect 
• sudo dpkg --set-selections < /media/usb/backup_all_settings/Package.list 
• sudo apt-get dselect-upgrade -y
