dpkg错误：“试图覆盖文件，这也是……”
例如：
$ sudo apt-get install curl Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: bsh : Depends: libjline-java but it is not going to be installed groovy : Depends: libjline-java but it is not going to be installed rhino : Depends: libjline-java but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). 当我尝试安装clojure1.3，leiningen和其他几个软件包时，我得到了相同或类似的错误。
当我尝试在错误消息中提出的建议时，会发生以下情况：

请不要直接使用danjjl答案 ，如果您遇到这种“试图覆盖”错误，可能是您需要首先解决的冲突包。
该问题的直接解决方法是删除不受欢迎的冲突包，在本例中为scala ，
sudo dpkg -P scala
接下来，建议与相应的软件包维护者一起提交错误报告。 这通常意味着在控制文件中添加Conflict: package行。
另请参阅此答案以获取有关此错误的更详细说明。
解决运行问题
sudo dpkg -i --force-overwrite /var/cache/apt/archives/libjline-java_1.0-1_all.deb
通过运行来检查所有内容： sudo apt-get -f install
如果您仍然遇到问题，请使用任何dpkg: error processing (...)重新运行第一步dpkg: error processing (...)剩余

@ danjjl的命令适用于.deb文件。 我发现这个命令适用于apt / apt-get ：
sudo apt-get -o Dpkg::Options::="--force-overwrite" install
不确定这是一个全局修复，因为我有同样的问题，但缓存中的libglx-mesa文件与Nvidia-390冲突。 我删除了文件并发出了apt install -f -y ，让它完成，然后按顺序继续进行apt update ， upgrade和autoremove 。
我在Ubuntu 18.04上执行apt dist-upgrade时遇到了错误并再次继续该过程，没有更多的问题，这似乎是“我的”修复。
命令：
sudo su - mv /var/cache/apt/archives/libglx-mesa0_18.0.0~rc5-1ubuntu1_amd64.deb ~ apt install -f -y apt update -y apt upgrade -y apt autoremove -y apt dist-upgrade
PS：强迫覆盖是一个坏主意，我尝试过，我很幸运。 但最好找到根本原因并修复它。 我仍然需要调查，但错误导致我将文件移出。
