我努力了此解决方案但是 dpkg 似乎也无法删除该依赖项。这是我尝试修复损坏的依赖项时的终端输出：

当我尝试删除该包（或其他包）时，这是我的终端输出：

答案1
您尝试安装包，但它与系统中已安装的libgranite5_5.3.0包发生冲突。libgranite-common 6.2.0
dpkg -P命令无法运行，因为其他一些软件包需要它。这里是libgranite6，甚至一些软件包也依赖于libgranite6。
作为一种解决方法，您可以使用 apt 命令来删除它以及依赖项：
sudo apt remove --autoremove libgranite-common
留意终端输出，它会告诉您在输入“y”并按回车键之前要删除哪些包。
或者，如果apt命令拒绝工作，请使用：
sudo dpkg -P libgranite6
它会删除该软件包，或者因为其他软件包依赖它而拒绝。您必须删除所有依赖软件包，才能安装libgranite5_5.3.0。
如果可能的话我建议使用Synaptic 软件包管理器对初学者更加友好。
