我尝试过的：
根据一篇文章debian-administration.org,
If the dependencies have changed on one of the packages you have installed so that a new package must be installed to perform the upgrade then that will be listed as "kept-back".
谨慎解决方案1：
每巴勃罗的回答，您可以运行sudo apt-get --with-new-pkgs upgrade，它将安装保留的软件包。
这样做的好处是不会将保留的软件包标记为“手动安装”，这可能会迫使更多的用户干预（请参阅评论）。
如果巴勃罗的解决方案适合您，请投票。如果没有，请评论哪里出了问题。
谨慎解决方案2：
谨慎的解决方案是运行sudo apt-get install <list of packages kept back>。在大多数情况下，这将为保留的软件包提供成功升级所需的信息。
积极的解决方案：
更积极的解决方案是运行sudo apt-get dist-upgrade，这将强制安装这些新的依赖项。
但dist-upgrade可能非常危险。与升级不同它可能会删除软件包以解决复杂的依赖情况。与您不同的是，APT 并不总是足够聪明，无法知道这些添加和删除是否会造成严重破坏。
因此，如果您发现自己处于“谨慎的解决方案”不起作用的地方，dist-upgrade可能会起作用......但您可能最好多了解一点 APT 并通过安装和删除“手动”解决依赖性问题包根据具体情况而定。
想象一下修理汽车……如果你有时间并且擅长使用扳手，那么通过阅读相关资料并自己进行修理，你会感到安心。如果你觉得自己很幸运，你可以把车交给你的表妹，dist-upgrade希望她知道该怎么做。
我也尝试过：

答案1
您已经添加了 Microsoft 存储库，其中包含较新版本的软件包odbcinst，并且这些存储库与 KDE 冲突（它们“破坏” libiodc2，这是 KDE 需要的）通过 soprano-daemon和libsoprano4）。
所以你需要选择：要么保留 KDE，要么升级到新的odbcinst软件包；你不能两者兼得。
要摆脱“警告”，您可以将 Microsoft 存储库固定为严格小于 100 的优先级，如下所示：
nano /etc/apt/preferences.d/proxmox
并插入：
