Debian Stretchにopenjdk-11-jre / jdkをインストールする方法は？

私のサーバーは現在Debian Stretchで実行されています。

Linux *** 4.9.0-8-AMD64＃1 SMP Debian 4.9.144-3.1（2019-02-19）x86_64 GNU/Linux

Openjdk-11-jdkをインストールしてみました。これは安定したストレッチの一部ではありません。だから私はソースにバックポートを追加しました 指示 ：

deb http://deb.debian.org/debian ストレッチバックポートメイン

パッケージのインストールは、使用できない依存関係に失敗しました：

536:root:/opt# apt-get update
[...]

537:root:/opt# apt-get -t stretch-backports install "openjdk-11-jdk"

1)     openjdk-11-jdk [Not Installed]
2)     openjdk-11-jre [Not Installed]

これらの依存関係を解決する方法がわかりません。

libgif7 パッケージのインストールに必要なstretch/main出力にapt policyリポジトリのエントリが見つかりません。

これを試して：

  • メインリポジトリを/etc/apt/sources.listに追加します。

    deb http://ftp.de.debian.org/debian stretch main

  • 次に実行します

    apt-get update
apt-get -t stretch-backports install openjdk-11-jdk
