在 Ubuntu 上安装 Mono-Complete 4.8

Question

我正在尝试在 Docker 映像中安装 Mono 4.8，但我无法下载。这是 dockerfile

`
  RUN apt-get update \
  && apt-get install -y curl \
  && rm -rf /var/lib/apt/lists/* \
  && apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys     3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF \
  && echo "deb http://download.mono-project.com/repo/debian wheezy main" >> /etc/apt/sources.list.d/mono-xamarin.list \
  && echo "deb http://download.mono-project.com/repo/debian wheezy-apache24-compat main" >> /etc/apt/sources.list.d/mono-xamarin.list \
  && echo "deb http://download.mono-project.com/repo/debian wheezy-libjpeg62-compat main" >> /etc/apt/sources.list.d/mono-xamarin.list \
  && apt-get update \
  && apt-get install -y clang \
  && apt-get install -y mono-complete=4.8.0.520-0xamarin3 
`

它无法安装 mono-compete 并出现此错误消息

`
E: Version '4.8.0.520-0xamarin3' for 'mono-complete' was not found `

我想知道 mono-complete 4.8 版本应该是什么？

将 version 固定到 snapshots 目录：

echo "deb http://download.mono-project.com/repo/ubuntu wheezy/snapshots/4.8.0.520 main" | sudo tee /etc/apt/sources.list.d/mono-official.list
sudo apt-get update

在 modifying/update 缓存之后，您可以使用 apt-cache policy {package} 来确定您要安装的版本是否可用。

>apt-cache policy mono-complete
mono-complete:
  Installed: (none)
  Candidate: 4.8.0.520-0xamarin3
  Version table:
     4.8.0.520-0xamarin3 500
        500 http://download.mono-project.com/repo/ubuntu wheezy/snapshots/4.8.0.520/main amd64 Packages
     4.6.2.7+dfsg-1ubuntu1 500
        500 http://us.archive.ubuntu.com/ubuntu artful/universe amd64 Packages

现在您可以安装 4.8.0.520-0xamarin3:

sudo apt-get install -y mono-complete=4.8.0.520-0xamarin3
