问题[bzip2](ubuntu)

我在 AWS EC2 t3a.nano 实例上运行 ubuntu 16.04.2 LTS (GNU/Linux 4.4.0-1087-aws x86_64)。当我通过 SSH 访问我的盒子时，我看到了这个：

Welcome to Ubuntu 16.04.2 LTS (GNU/Linux 4.4.0-1087-aws x86_64)

 * Documentation:  [redacted]
 * Management:     [redacted]

132 packages can be updated.
3 updates are security updates.

为了使我的盒子上的软件保持最新状态，我运行了：

sudo apt-get update
Hit:1 [redacted] xenial InRelease
Hit:2 [redacted] xenial-updates InRelease
Hit:3 http://us-east-2.ec2.archive.ubuntu.com/ubuntu xenial-backports InRelease
Hit:4 http://security.ubuntu.com/ubuntu xenial-security InRelease

然后我输入：

sudo apt-get upgrade
Reading package lists... Done
Building dependency tree

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
E: Unmet dependencies. Try using -f.

好的，所以我看到我有依赖问题，所以我尝试：

sudo apt-get -f install

现在我看到 dpkg 意外退出，我尝试：

sudo dpkg --audit
The following packages are in a mess due to serious problems during
installation.  They must be reinstalled for them (and any packages
that depend on them) to function properly:

我尝试：

sudo apt-get install bzip2

Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 bzip2 : Depends: libbz2-1.0 (= 1.0.6-8ubuntu0.2) but 1.0.6-8ubuntu0.1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

所以现在我尝试：

sudo apt-get -f install
Reading package lists... Done

Correcting dependencies... Done
The following additional packages will be installed:
  bzip2 libbz2-1.0

现在我要绕圈子了。有任何想法吗？

编辑以解决来自@fkraiem 的评论：当我转到 /etc/apt/sources.list 时，我看到：

## Note, this file is written by cloud-init on first boot of an instance
## modifications made here will not survive a re-bundle.
## if you wish to make changes you can:
## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg
##     or do the same in user-data
## b.) add sources in /etc/apt/sources.list.d
## c.) make changes to template file /etc/cloud/templates/sources.list.tmpl

您是否建议我将 us-east-2.ec2.archive.ubuntu.com 替换为 packages.ubuntu.com 并重试更新命令？

我需要为压缩文件做一个前端，这个想法是如果你收到一个 gz 或 bz2 文件，用 gunzip 和 bunzip2 解压缩它。

如果您收到的是 tar.gz 或 tar.b2，您应该使用 tar xzf 或 xjf 解压并解压缩一次。我的代码如下

#!/bin/bash

if test $# -ne 1
then
    echo "Numero de parametros incorrecto"
    echo "Uso del programa: $0 archivo"
    exit 1;
fi

case "$1" in
    *.gz)
        echo "gzip"
        echo "Descomprimiendo"
        `gunzip $1`
    ;;
    *.bz2)
        echo "bzip2"
        echo "Descomprimiendo"
        `bunzip2 $1`
    ;;
    *.tar.gz)
        `tar xzvf $1`
    ;;
    *.bzip2.gz)
        `tar xjvf $1`
    ;;
esac

问题是，即使我传递了一个扩展名为 .tar.gz 的文件，我输入了案例的第一个条件，我试图添加美元以严格限制它以这样的方式结束，但它不起作用

我想将两个或多个文件压缩到一个文件中，我检查了这个和这个，但两者都有类似的文件：n1.txt，，n2.txt......但我的文件名完全不同，比如：，，file.mp4我想将它们全部压缩并放置输出到一个文件中。这也没有帮助：bar.txtfoo.jpeg

gzip -c file.mp4 > test.gz
gzip -c bar.txt >> test.gz

我必须先将它们焦油吗？

还有一个问题：在 tar 文件中，我们可以在不解压的情况下观看内部文件：

tar -tvf filename.tar

无论如何用gzip或bzip2来做到这一点？

我正在尝试为在 CUDA 中实现的神经网络构建这个 repo。

我已按照该链接中的说明在外壳上执行了以下操作：

git clone https://github.com/ANNetGPGPU/ANNetGPGPU.git
cd ANNetGPGPU
mkdir build
cd build
cmake .. && make

但是，当我写最后一行时，返回以下错误：

CMake Error at /home/iibm/Documents/martins/cmake-3.12.1-Linux-x86_64/share/cmake-3.12/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

See also "/home/iibm/Documents/martins/ANNetGPGPU/build/CMakeFiles/CMakeOutput.log".

但 bzip2 肯定已安装，bzip2 --version返回：

bzip2, a block-sorting file compressor.  Version 1.0.6, 6-Sept-2010.

那么我该如何解决这个问题，为什么会这样呢？
