检查并删除未使用的 PPA

自安装以来，我向 15.04 系统添加了不少 PPA，因为我想要一个特定的应用程序。但有时我稍后会再次删除该包，因为它不起作用，不是我真正想要的，或者只是因为我不再需要它。我不知道这是否有区别，但有些存储库是随系统一起安装的，add-apt-repository而其他存储库只是通过手动创建文件的命令安装的/etc/apt/sources.list.d/。

现在我该如何检查我是否安装了来自 PPA 的任何软件包？如果没有，如何从我的软件源中删除它？此过程应自动适用于所有 PPA。

这是一个脚本。如果没有参数，脚本会列出一些信息。如果使用--delete，则list文件将被删除，如果不软件包已安装。

#!/usr/bin/env bash
for f in /etc/apt/sources.list.d/*.list; do
    grep -Po "(?<=^deb\s).*?(?=#|$)" "$f" | while read -r ENTRY ; do
    echo "ENTRY: $ENTRY"

    # Sanitize entry line by removing stuff between square brackets
    ENTRY=$(echo "$ENTRY" | sed 's/\[.*\] //')

        HOST=$(cut -d/ -f3 <<< "$ENTRY")

        if [ "ppa.launchpad.net" = "$HOST" ]; then
          USER=$(cut -d/ -f4 <<< "$ENTRY")
          PPA=$(cut -d/ -f5 <<< "$ENTRY")
          packageCount=$(sed -e '/^Package:/!d' -e 's/Package: \(.*\)$/\1/g' /var/lib/apt/lists/*"$USER"*"$PPA"*Packages | xargs dpkg -l 2>/dev/null | grep -c '^ii')
          echo "PPA: ppa:$USER/$PPA"
          echo "FILENAME: $f"
          echo "$packageCount package(s) installed"
          if [ "$packageCount" -eq 0 ] && [ "$1" == "--delete" ]; then
            sudo rm "$f" && echo "$f deleted"
          fi
          echo
        else 
          USER=$(cut -d/ -f3 <<< "$ENTRY")
          PPA=$(cut -d/ -f4 <<< "$ENTRY")
          packageCount=$(sed -e '/^Package:/!d' -e 's/Package: \(.*\)$/\1/g' /var/lib/apt/lists/*"$USER"*Packages | xargs dpkg -l 2>/dev/null | grep -c '^ii')
          echo "REPOSITORY: $USER/$PPA"
          echo "FILENAME: $f"
          echo "$packageCount package(s) installed"
          if [ "$packageCount" -eq 0 ] && [ "$1" == "--delete" ]; then
            sudo rm "$f" && echo "$f deleted" 
          fi
          echo
        fi
    done
done

将上述代码复制到新文件中，例如：

mkdir -p ~/bin
nano ~/bin/checkPPAs

使脚本可执行

chmod +x ~/bin/checkPPAs

然后运行它

~/bin/checkPPAs

列出所有存储库和已安装的软件包的数量。

使用以下命令启动脚本

~/bin/checkPPAs --delete

删除list文件。

答案2

我不知道有没有自动化的方法，但是这种方法相当快：

  1. 启动 synaptic 包管理器并在出现提示时输入密码

  2. 在左下角，点击起源

现在，系统上的所有 ppa 都将列在左栏顶部。您可以单击列表，查看每个 ppa 中是否安装了任何软件。（如果有，右栏中软件包名称旁边会有一个绿色框）。如果 ppa 中有许多软件包（太多而无法一次在屏幕上看到），您可以单击年代按状态对它们进行排序。

笔记：如果您有任何未使用的 ppa：

  1. 点击设置在顶部菜单中
  2. 然后存储库
  3. 软件和更新 将显示窗口。
  4. 从此窗口中，你可以从中删除未使用的 ppa其他软件标签。

答案3

在看到接受的答案有一个关键错误后，我不得不修复它并将其发布在这里。

AB 的答案遍历每个list文件中的条目，如果该文件中的任何条目在系统上安装了 0 个包，则无论有多少条目有包，它都会删除整个文件。

它还会完全忽略任何不符合预定义格式的条目。它不会考虑这些条目。

该脚本还会处理匹配的条目。它不会触碰空文件。

因此我修改了脚本如下：

#!/usr/bin/env bash
for f in /etc/apt/sources.list.d/*.list; do
    fileTotal=0
    echo "FILENAME: $f"

    while read -r ENTRY ; do
        echo "ENTRY: $ENTRY"

        # Sanitize entry line by removing stuff between square brackets
        ENTRY=$(echo "$ENTRY" | sed 's/\[.*\] //')

        HOST=$(cut -d/ -f3 <<< "$ENTRY")

        if [ "ppa.launchpad.net" = "$HOST" ]; then
          USER=$(cut -d/ -f4 <<< "$ENTRY")
          PPA=$(cut -d/ -f5 <<< "$ENTRY")
          packageCount=$(awk '$1=="Package:" {if (a[$2]++ == 0) {system("dpkg -l "$2)}}' /var/lib/apt/lists/*"$USER"*"$PPA"*Packages 2>/dev/null | awk '/^ii/' | wc -l)
        else 
          USER=$(cut -d/ -f3 <<< "$ENTRY")
          PPA=$(cut -d/ -f4 <<< "$ENTRY")
          packageCount=$(awk '$1=="Package:" {if (a[$2]++ == 0) {system("dpkg -l "$2)}}' /var/lib/apt/lists/*"$USER"*Packages 2>/dev/null | awk '/^ii/' | wc -l)
        fi

        ((fileTotal+=packageCount))
        printf '\t%s\n' "REPOSITORY: $USER/$PPA"
        printf '\t%s\n' "$packageCount package(s) installed"
        echo
    done < <(grep -Po "(?<=^deb\s).*?(?=#|$)" "$f")

#    unrecognizedCount=$(grep -Pv "(?=^deb\s)|(?=^#).*" "$f" | grep -Pc "[^\s]")
    unrecognizedCount=0
    while read -r ENTRY ; do
        ((unrecognizedCount++))
        printf '\t%s\n' "Unrecognized entry: $ENTRY"
    done < <(grep -Pv "(?=^deb\s)|(?=^#).*" "$f" | grep -P "[^\s]")

    echo "$fileTotal packages installed"
    echo "$unrecognizedCount entries unrecognized"

    if [ "$fileTotal" -eq 0 ] && [ "$unrecognizedCount" -eq 0 ]; then
      if [ "$1" == "--delete" ]; then
          sudo rm "$f"
          sudo rm "$f".*
          echo "$f deleted"
      else
          echo "Deletable"
      fi
    fi

    echo "----------------------------"
done

用法完全相同，只是--delete选项仅在没有任何已安装软件包的条目和未识别的条目时才删除文件。空白行和注释行不算作条目。

即使我考虑了所有我能考虑的，这仍然是未经测试的、可以安全运行的脚本sudo。请备份/etc/apt/sources.list.d目录中的所有内容。
