從 Debian 8 (Jessie) 升級到 9 (Stretch)

Question

我正在將 Debian 8 (Jessie) 機器更新到 Debian 9 (Stretch)

目前核心版本是：

# uname -a
Linux host 4.9.0-0.bpo.6-amd64 #1 SMP Debian 4.9.88-1+deb9u1~bpo8+1 (2018-05-13) x86_64 GNU/Linux

現在我已經確保我的所有軟體包在 Debian 8 上都是最新的。

# apt update
.
.
.
Reading package lists... Done
Building dependency tree
Reading state information... Done
All packages are up to date.

我的/etc/apt/sources.list.d/資料夾包含以下內容：

# ls -ltrh
total 16K
-rw-r--r-- 1 root root 575 Nov 22  2017 jessie.list
-rw-r--r-- 1 root root  72 Nov 22  2017 download_docker_com_linux_debian.list
-rw-r--r-- 1 root root  93 Jan 18  2018 jessie-backports.list

作業系統詳細資料是：

# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 8 (jessie)"
NAME="Debian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
ID=debian
HOME_URL="http://www.debian.org/"
SUPPORT_URL="http://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

現在，作為我實際升級到 Debian 9 的一部分，我在下面添加了以下文件/etc/apt/sources.list.d/：

# cat  stretch.list


deb https://my-repository.com/debian/       stretch         main contrib non-free
deb https://my-repository.com/debian/       stretch-updates     main contrib non-free
deb https://my-repository.com/debian/   stretch-proposed-updates    main contrib non-free

deb https://my-repository.com/debian-security/  stretch/updates     main contrib non-free

現在我已經添加了這個文件，我做了一個apt update，可以看到它確實正在讀取拉伸源。

當我做一個apt upgrade它什麼都不做並說All packages are up to date.

下面2條命令返回0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

# apt upgrade

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

# apt dist-upgrade

它似乎沒有升級到 Debian 9。

您禁用了 Jessie 儲存庫嗎？如果沒有，請嘗試執行，apt update && apt upgrade如果成功則嘗試執行apt dist-upgrade並重新啟動以完成並確認升級。
