E: Unable to locate package 问题

case1

• 是否拼写错包名(可以用sudo apt-cache search <packageNane>配合grep 通配符获取完整包名)

apt 搜索可用包

• 譬如:sudo apt-cache search "dict-"|grep ^dict-|less

  • dict-de-en - German-English translation dictionary for dictd
    dict-devil - "The Devil's Dictionary" by Ambrose Bierce
    dict-elements - Data regarding the Elements
    dict-foldoc - FOLDOC dictionary database
    dict-freedict-afr-deu - Afrikaans-German dictionary for the dict server/client
    dict-freedict-afr-eng - Afrikaans-English dictionary for the dict server/client
    dict-freedict-ara-eng - Arabic-English dictionary for the dict server/client
    dict-freedict-bre-fra - Breton-French dictionary for the dict server/client
    dict-freedict-ces-eng - Czech-English dictionary for the dict server/client
    dict-freedict-ckb-kmr - Central Kurdish-Northern Kurdish dictionary for the dict server/client
    dict-freedict-cym-eng - Welsh-English dictionary for the dict server/client

• 或者sudo apt list |grep dict

case2

• 是否源不够完善/过于老旧(换一个更好的源,或者使用sudo apt update 更新一下缓存)
  • 也可能需要扩充仓库源

case3

• 是否目标工具包是从属于某个工具集合包,则可以通过安装工具集来间接安装相应工具
  • 

修改源的命令行工具(add-apt-repository)的安装

以下针对ubuntu(其他debian衍生版情况未必如此,譬如kali)

• sudo apt-get install software-properties-common -y

• sudo apt update -y

• 此时,add-apt-repository应该可以使用了

  • sudo add-apt-repository universe
    sudo add-apt-repository multiverse
    sudo apt update

  • 如果add-apt-repository不可用,则尝试:

    • sudo apt install add-apt-repository -y
    • 现在,可以借助add-apt-repository来添加/删除自己系统的源(repository)
    • 操作完毕后,再次执行sudo apt update

add-apt-repository命令不是必须的,我们完全可以手动修改源

install errno command line package

ubuntu 安装errno工具

• sudo apt install errno -y
  • errno -l查看errno代码的解释

kali 安装errno工具

• errno(3) - Linux manual page (man7.org)

the errno(1) command (part of the moreutils package)

可知,我们或许能够通过安装moreutils工具集,来间接安装errno
