我刚从源代码安装了Python 3.6.1,然后运行sudo pip3 install readline安装readline模块.但是当我启动Python shell时,无论我输入什么,它都会崩溃:

只需执行caller.py …

我试图在Ubuntu中通过apt-get安装android-studio,并发现需要从Google下载大小为233 M的依赖包.由于我在中国,网络状况非常糟糕,我无法完全下载软件包,最后我不得不放弃.
然而,这里出现了一个问题:现在每次执行时apt-get我都会得到一些提示Incomplete dependency并被要求下载上面的包.如果我执行sudo apt-get remove android-studio错误将发生:

dpkg: error processing package android-studio (--remove):
package is in a very bad inconsistent state; you should
reinstall it before attempting a removal
An error occurred when processing:
android-studio
E: Sub-process /usr/bin/dpkg returned an error code (1)

我apt-get被困住了.那我怎么能完全删除一个不完整的包呢？

这是我的服务文件：

当我执行时，sudo systemctl start daphnei我得到：

See system logs and 'systemctl status daphnei.service' for details.

和的结果systemctl status daphnei.service：
