什么是 dpkg-reconfigure，它与 dpkg --configure 有何不同？

  • 772

我最近得到了另一个问题的答案帮助：“aptd”正在用尽我的 CPU？其中包括运行命令

sudo dpkg-reconfigure -phigh -a

和

sudo dpkg --configure -a

这一切似乎都很合理，但我对一些事情感到好奇。

dpkg-reconfigure这些-phigh -a标志是什么意思？

它与 有何不同dpkg --configure？

apt

    从man dpkg

       --configure package...|-a|--pending
          Configure a package which has been unpacked but not yet  config‐
          ured.   If  -a  or  --pending  is  given instead of package, all
          unpacked but unconfigured packages are configured.

          Configuring consists of the following steps:

          1.  Unpack  the  conffiles, and at the same time back up the old
          conffiles, so that they can be restored if something goes wrong.

          2. Run postinst script, if provided by the package.

    从man dpkg-reconfigure

       dpkg-reconfigure - reconfigure an already installed package

   -pvalue, --priority=value
       Specify the minimum priority of question that will be displayed.
       dpkg-reconfigure normally shows low priority questions no matter
       what your default priority is. See debconf(7) for a list.

   -a, --all
       Reconfigure all installed packages that use debconf. Warning: this
       may take a long time.

    这里dpkg --configure -a将配置所有解压但未配置的包。而dpkg-reconfigure -phigh -a将重新配置所有已安装debconf的高优先级软件包。
