近两周以来，我一直在尝试更新我的 24.04 系统，但大多数更新都被阻止了。是否存在分发问题阻止了更新，还是我的系统出了问题？今天，有 718 个更新，但只安装了 2 个，其余的都被阻止了。
起初，我以为这是一个分阶段更新问题，所以我每天都在执行 apt update / apt upgrade 命令，但毫无进展。我被告知分阶段更新大约需要一周时间才能完成，所以我看到的情况似乎有些过分。
升级到 24.04.1 失败，并显示一条消息，提示我需要在安装之前进行所有更新。如您在附加日志中看到的，我已尝试进行所有更新，但某些“esm-apps”更新未安装，我需要安装 Ubuntu Pro 来更新它们。我假设这些更新不是进行更新所必需的。
有一系列 dotnet 更新未安装，但我之前已删除 dotnet。这些更新是否阻碍了升级？如果是，我可以删除它们吗？
顺便说一句，我也尝试了软件更新程序，但它退出时没有任何消息。:-(
