Upgrading from wheezy to jessie on Raspberry Pi

遅ればせながら、、、jessieへ

実証ロボットのコントローラのアップデート

手順は

(1) Wheezy のアップデート

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade

(2)apt-getの環境設定ファイルの更新（文字列wheezyをjessieに変更） 

$ sudo vi /etc/apt/sources.list
$ sudo vi /etc/apt/sources.list.d/collabora.list
$ sudo vi /etc/apt/sources.list.d/raspi.list

(3)jessie へ

$sudo apt-get update

でエラー
collabora.comを使っていないそうなので、コメントアウト

$ sudo vi /etc/apt/sources.list.d/collabora.list
$ cat /etc/apt/sources.list.d/collabora.list
#deb http://raspberrypi.collabora.com jessie rpi
#deb http://raspberrypi.collabora.com wheezy rpi

修正して、再度
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade

途中で、いろいろ聞いてくるので入力をしながら、、、

(4) reboot

$ sudo reboot

(5) 確認

$ lsb_release -a
   No LSB modules are available.
   Distributor ID: Raspbian
   Description:    Raspbian GNU/Linux 8.0 (jessie)
   Release:        8.0
   Codename:       jessie

(6) 後始末

$ sudo apt-get autoremove
$ sudo apt-get autoclean

Peace!
