Mono是一个开源项目，由Xamarin（现在由Microsoft拥有）开发，为Linux，macOS和其他平台提供一套与.NET框架兼容的工具。它允许开发人员在非Windows平台上构建和运行.NET应用程序。这包括对 .NET 库和框架（如 ASP.NET 和 WPF）的支持。
在 Ubuntu 22.04 LTS Jammy Jellyfish 上安装 Mono
第 1 步。首先，通过在终端中运行以下命令，确保所有系统软件包都是最新的。apt
<span class="pln">sudo apt update sudo apt upgrade sudo apt install dirmngr gnupg apt</span><span class="pun">-</span><span class="pln">transport</span><span class="pun">-</span><span class="pln">https ca</span><span class="pun">-</span><span class="pln">certificates software</span><span class="pun">-</span><span class="pln">properties</span><span class="pun">-</span><span class="pln">common</span>
第 2 步。在 Ubuntu 22.04 上安装 Mono。
默认情况下，Mono 在 Ubuntu 22.04 基本存储库上不可用。现在运行以下命令，将 MonoDevelop 存储库添加到您的 Ubuntu 系统中：
<span class="pln">echo </span><span class="str">"deb https://download.mono-project.com/repo/ubuntu stable-focal main"</span> <span class="pun">|</span><span class="pln"> sudo tee </span><span class="pun">/</span><span class="pln">etc</span><span class="pun">/</span><span class="pln">apt</span><span class="pun">/</span><span class="pln">sources</span><span class="pun">.</span><span class="pln">list</span><span class="pun">.</span><span class="pln">d</span><span class="pun">/</span><span class="pln">mono</span><span class="pun">-</span><span class="pln">official</span><span class="pun">-</span><span class="pln">stable</span><span class="pun">.</span><span class="pln">list</span>
接下来，使用以下命令导入 GPG 密钥：
<span class="pln">sudo apt</span><span class="pun">-</span><span class="pln">key adv </span><span class="pun">--</span><span class="pln">keyserver hkp</span><span class="pun">:</span><span class="com">//keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF</span>
启用存储库后，现在使用以下命令安装最新版本的 Mono：
<span class="pln">sudo apt update sudo apt install mono</span><span class="pun">-</span><span class="pln">devel</span>
要验证 Mono 是否已成功安装，请在终端窗口中输入以下命令：
<span class="pln">mono </span><span class="pun">--</span><span class="pln">version</span>
输出：
<span class="typ">Mono</span><span class="pln"> JIT compiler version </span><span class="lit">6.30</span><span class="pun">.</span><span class="lit">0.182</span> <span class="pun">(</span><span class="pln">tarball </span><span class="typ">Fri</span> <span class="typ">Dec</span> <span class="lit">16</span> <span class="lit">16</span><span class="pun">:</span><span class="lit">36</span><span class="pun">:</span><span class="lit">00</span><span class="pln"> UTC </span><span class="lit">2021</span><span class="pun">)</span> <span class="typ">Copyright</span> <span class="pun">(</span><span class="pln">C</span><span class="pun">)</span> <span class="lit">2002</span><span class="pun">-</span><span class="lit">2014</span> <span class="typ">Novell</span><span class="pun">,</span> <span class="typ">Inc</span><span class="pun">,</span> <span class="typ">Xamarin</span> <span class="typ">Inc</span> <span class="kwd">and</span> <span class="typ">Contributors</span><span class="pun">.</span><span class="pln"> www</span><span class="pun">.</span><span class="pln">mono</span><span class="pun">-</span><span class="pln">project</span><span class="pun">.</span><span class="pln">com TLS</span><span class="pun">:</span><span class="pln"> __thread SIGSEGV</span><span class="pun">:</span><span class="pln"> altstack </span><span class="typ">Notifications</span><span class="pun">:</span><span class="pln"> epoll </span><span class="typ">Architecture</span><span class="pun">:</span><span class="pln"> x86 </span><span class="typ">Disabled</span><span class="pun">:</span><span class="pln"> none M</span>
