我正在尝试删除
libnvidia-compute-440_440.36-0ubuntu0~0.18.04.1_amd64.deb
root@miki:/var/cache/apt/archives# sudo dpkg --remove libnvidia-compute-440_440.36-0ubuntu0~0.18.04.1_amd64.deb
这没用
dpkg: error: --remove needs a valid package name but 'libnvidia-compute-440_440.36-0ubuntu0~0.18.04.1_amd64.deb' is not: illegal package name in specifier 'libnvidia-compute-440_440.36-0ubuntu0~0.18.04.1_amd64.deb': character '~' not allowed (only letters, digits and characters '-+._')
有哪些替代方案？
我运行这个脚本来创建用户和组
groupadd hadoop
useradd -g hadoop yarn
useradd -g hadoop hdfs
useradd -g hadoop mapred
但是如果我尝试登录
miki@miki:~$ su - hdfs
Password:
su: Authentication failure
我没有为我的 hdfs 用户提交任何密码。
cut -d: -f1 /etc/passwd output
yarn
hdfs
mapred
如何解决这个问题呢？
我的朋友给了我一个带有 ISO 格式教程的 USB 当我尝试在我的 Ubuntu 18.04 上打开它们时，我得到了这个
如果我选择开始恢复，它是否会擦除我 500GB 磁盘上的所有其他内容？
我正在阅读 Python 网络书：
当网络设备产生需要通过网络发送的网络流量时，它首先将目的地的 IP 地址与其自己的网络前缀进行比较。

我插入了我的 MD Elements 硬盘。我无法安装它，这是我第一次遇到这样的问题。
Error mounting /dev/sdc1 at /media/milenko/Elements: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sdc1" "/media/milenko/Elements"' exited with non-zero exit status 13: $MFTMirr does not match $MFT (record 0)
我对此感到困惑。 MFTMirr 代表什么？如何解决这个问题？
我已经格式化了我的笔记本电脑，没有检测到无线。

我想在 virtualbox 上与我的 Windows 10 共享它。但是当我选择网络时
但是文件夹是空的。我的Linux文件夹在哪里？一直没有被识别，为什么？我的防火墙未激活
sudo ufw status

这是我在 Windows 中的网络配置
我有问题，我已经按照这个建议，但是重启后终端无法打开。
如果我gnome-terminal从 xterm 运行：

我现在该怎么办？
我工作了很多，但我不确定是否一切正常。

which nvcc

但是我的安装目录是
