我在 Ubuntu 上安装 KDE plasma，但是电源被切断了。当我尝试重新安装时，出现错误。

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
kde-telepathy-minimal : Depends: kde-config-telepathy-accounts (>= 15.04.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我尝试使用sudo apt-get --purge remove kubuntu-desktop，但失败了。使用sudo apt-get -f install无效。
The following additional packages will be installed:
kde-config-telepathy-accounts
The following NEW packages will be installed:
kde-config-telepathy-accounts

我也使用过sudo dpkg --remove --force-remove-reinstreq kubuntu-desktop，它成功完成，但没有效果。我无法安装 synaptic，也无法升级软件包。我也无法删除google-im.service

只需运行：
sudo dpkg -i --force-all /var/cache/apt/archives/kde-config-telepathy-accounts_4%3a15.12.3-0ubuntu1_i386.deb
这将重新安装软件包，并强制覆盖文件。这个问题通常发生在将文件从一个软件包移动到另一个软件包时，由于存储库不是完全最新的，或者像你的情况一样，安装中断，新文件无法解压，因为它似乎与另一个软件包冲突。
上述命令的作用是使 dpkg 忽略所有错误（通过使用标志--force-all）。您也可以使用--force-overwrite。
