无法将 Java 从 Java 7 更新至 Java 8

我正在尝试将 Ubuntu 服务器上的 Java 更新到 Java 8，但收到一条错误消息，并且 Java 无法更新。

error message: Errors where encountered while processing E: Sub-process /usr/bin/dpkg returned an error code (1)

我用了：

sudo add-apt-repository ppa:webupd8team/java

然后：

sudo apt update

出现错误：

Failed to fetch ......binary-amd64/Packages 404 not found
Failed to fetch ......binary-i386/Packages 404 not found
E: some files failed to download. Thay have been ignored,or old ones used instead.

然后：

sudo apt install oracle-java8-installer

出现错误：

E: Sub-process /usr/bin/dpkg returned an error code (1)

我也尝试过sudo apt-get -f install并且给出了这个输出：

Debconf : DbDriver "config" : /var/cache/deconf/config.dat is locked by another process: resource temorarily unavalable
Dpkg: error processing pacage openssh-server (--configure):
 Subprocess installed post-instalation script returned error exit status 2
Errors were encountered while processing:
 openssh-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

我已经有一年没有使用我的 16.10 服务器了，而且它已经两年没有更新了。

我使用sudo apt-get update并得到了这个输出：

Ubuntu 16.10 Yakkety Yak is no longer supported by Canonical (and thus, Launchpad and this PPA). The PPA supports Ubuntu 17.10, 17.04, 16.04, 14.04 and 12.04.

答案1

没有名为oracle-java8-安装程序在 ppa:webupd8team/java 中。包的正确名称是 oracle-java-8-installer。打开终端并输入：

sudo apt update  
sudo apt install oracle-java-8-installer

或者，您可以从所有当前支持的 Ubuntu 版本中的默认存储库安装 Java 8。使用 从软件源中删除 ppa:webupd8team/java 存储库sudo apt-add-repository --remove ppa:webupd8team/java，使用 更新软件包列表sudo apt-get update并运行以下命令：

sudo apt install openjdk-8-jdk

如果仍然收到Debconf : DbDriver "config" : /var/cache/deconf/config.dat is locked by another process: resource temporarily unavailable错误消息，请按照以下答案解决安装软件包时出现“debconf：DbDriver“config”：config.dat 被另一个进程锁定：资源暂时不可用”。

答案2

W: Failed to fetch http: 
/ppa.launchpad.net/thefrontiergroup/vsftpd/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found
W: Failed to fetch http: 
/ppa.launchpad.net/thefrontiergroup/vsftpd/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

这些错误表明这两个 ppa 不再存在。将它们从/etc/apt/sources.list和中删除/etc/apt/sources.list.d

没有理由拥有它们，因为 vsftp 存在于主存储库中。

另外我建议您升级到 17.10，因为 16.10 不再受支持。

一旦存储库被删除，

sudo apt update

应该可以工作，然后您就可以安装 Java 8。
