我的/etc/apt/sources.list包含：

deb http://ubuntu.mirror.garr.it/ubuntu/ focal main
deb-src http://ubuntu.mirror.garr.it/ubuntu/ focal main

deb-src http://ubuntu.mirror.garr.it/ubuntu/ focal restricted universe multiverse

deb http://ubuntu.mirror.garr.it/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://ubuntu.mirror.garr.it/ubuntu/ focal-updates main restricted universe multiverse

deb http://ubuntu.mirror.garr.it/ubuntu/ focal-security main restricted universe multiverse
deb-src http://ubuntu.mirror.garr.it/ubuntu/ focal-security main restricted universe multiverse

deb http://ubuntu.mirror.garr.it/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://ubuntu.mirror.garr.it/ubuntu/ focal-backports main restricted universe multiverse

deb http://archive.canonical.com/ubuntu focal partner
deb-src http://archive.canonical.com/ubuntu focal partner

但是当我尝试与软件更新相关的任何事情时，例如， sudo apt update --fix-missing && sudo apt upgrade我在终端上得到以下输出：

    sudo apt update --fix-missing && sudo apt upgrade
Err:1 http://archive.canonical.com/ubuntu focal InRelease

Err:2 http://ubuntu.mirror.garr.it/ubuntu focal InRelease

  Temporary failure resolving 'proxy_server'
Err:4 http://ubuntu.mirror.garr.it/ubuntu focal-security InRelease

Err:5 http://ubuntu.mirror.garr.it/ubuntu focal-backports InRelease

我尝试安装的任何东西都会出现类似的问题：

$ sudo apt-get install indicator-cpufreq

E: Unable to locate package indicator-cpufreq

尝试从Software update应用程序更改服务器卡在缓存刷新中，或最终返回类似于Failed to fetch one（窗口不允许我复制和粘贴输出错误）的错误。

有关我的系统的更多信息：

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.4 LTS
Release: 20.04
Codename: focal

什么应该进入services.listand proxy，问题可能是什么？

编辑＃1：我认为我/etc/apt/apt.conf错了，我希望能在该文件中提供一些帮助。echo "$http_proxy"不返回任何东西，也不返回任何东西env | grep -i proxy。设置 --> 代理网络设置为禁用，但如果我检查Manual我进入proxy-server-ip“代理 HTTP”字段并且8080是端口。

编辑#2：我的/etc/apt/apt.conf.d/proxy.conf包含两行：

Acquire::http::Proxy "http://proxy_server:port/";
Acquire::https::Proxy "http://proxy_server:port/";
apt proxy

如何解密存储在级联子目录中的文件gpg？类似于bash脚本的东西：

要从我在终端中使用的给定文件夹中提取单个 .Z 文件uncompress file.Z，它可以完美运行。如果在同一个文件夹中，我想提取我使用的所有 .Z 文件uncompress "*.Z"oruncompress '*.Z'或uncompress \*.Z. 但他们都给出了同样的错误：

gzip: *.Z: No such file or directory

（我使用了各种形式的引号只是为了表明引号不应该是问题）。

如果我使用每个文件的“扩展”扩展名，即file.fitz.Z. 如何解压缩所有 .Z 文件？出了什么问题？

PS：这已经在SO上发布了，但是还没有运气（尽管我无法想象这个问题很难回答）。

ubuntu gzip
