DNS解析因未知原因失敗
在我的 64 位 kali linux 中安裝 jdk 8 時出現以下錯誤。

如果我執行
wget http://download.oracle.com/otn-pub/java/jdk/8u111-b14/jdk-8u111-linux-x64.tar.gz它工作正常。也可以
nslookup google.com正常ping google.com工作。我也刪除了文件中的所有內容，
/var/cache/oracle-jdk8-installer/wgetrc但同樣的問題。請幫忙！
那是奇特的問題。
DNS 並沒有因為某些奇怪的原因而失敗，您的 DNS 工作正常。但是，您嘗試的軟體包似乎帶有損壞的安裝後腳本，該腳本將“false”作為主機名並將其傳遞給 wget，而不是預期的主機名。
從輸出中可以明顯看出：

解決假（假）…失敗：名稱或服務未知。
wget：無法解析主機地址“假”
如果我想更深入地研究它，我會查看 /var/cache/oracle-jdk8-installer/wgetrc 看看那裡是否有問題，
apt-get clean然後重試。我建議你嘗試實現這個結果 - 使用替代方法安裝 java，例如這裡描述的http://www.2daygeek.com/install-oracle-java-using-java-alternatives-method-on-ubuntu-centos-debian -fedora-mint-rhel-opensuse/看看它是否適合你——這可能是最快的。
