我看到 ubuntu 需要循环安装然后卸载 4 个软件包。以下是控制台的一些输出：
$ sudo apt autoremove
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 to upgrade, 0 to newly install, 0 to remove and 2 not to upgrade.
$ sudo apt upgrade
Reading package lists... Done

The following packages were automatically installed and are no longer required:
libcec4 libp8-platform2 libva-drm1
Use 'sudo apt autoremove' to remove them.
The following NEW packages will be installed
libcec4 libp8-platform2 libva-drm1
The following packages have been kept back:
kodi kodi-bin
0 to upgrade, 3 to newly install, 0 to remove and 2 not to upgrade.
Need to get 229 kB of archives.
After this operation, 777 kB of additional disk space will be used.

Abort.
忽略 Kodi 包，我并不急于从 16.1 升级到 17.0。
注意：我没有列出sudo apt update您所期望的内容。如果我单击安装所述软件包，则自动删除将要求我删除它们。我认为这个问题是在我从以前的 ppa 卸载 nexcloud-client 软件包并从 nextcloud-dev ppa 重新安装它后出现的，但我不确定。
关于我应该怎样修复此问题，您有什么想法吗？
编辑-更新：
关于第一条评论，在给出上述结果的同一终端上：
sudo apt-mark manual libcec4
libcec4 can not be marked as it is not installed.
还：
$ apt-cache policy libcec4
libcec4:
Installed: (none)
Candidate: 4.0.1.1~xenial
Version table:
4.0.1.1~xenial 500
500 http://ppa.launchpad.net/team-xbmc/ppa/ubuntu xenial/main amd64 Packages
嗯，这似乎与 kodi 有关，也许这些包是 17.0 所需的？
答案1
根据@user535733的建议，我通过输入将有问题的包设置为手动
sudo apt-mark manual libcec4 libp8-platform2 libva-drm1
PS 我可以将系统升级到 kodi17 来看看会发生什么，但是我还没有时间学习新的界面并根据我的用例重新配置它。
