在 Ubuntu 20.04 上从 linuxuprising PPA 安装 Shutter 时出现“损坏的软件包”错误

04 我想重新安装 Shutter。

我按照以下说明进行操作https://www.linuxuprising.com/2018/10/shutter-removed-from-ubuntu-1810-and.html（据称也适用于 20.04）

sudo add-apt-repository ppa:linuxuprising/shutter
sudo apt-get update
sudo apt install shutter

但是 Shutter 仍然无法安装：

 ~  sudo apt install shutter

The following information may help to resolve the situation:

The following packages have unmet dependencies.
 shutter : Depends: libgnome2-perl but it is not going to be installed

有什么想法我可以如何安装它吗？

编辑：

sudo apt-cache policy shutter
shutter:
  Installed: (none)
  Candidate: 0.94.3-1~0linuxuprising1~focal1
  Version table:
     0.94.3-1~0linuxuprising1~focal1 500
        500 http://ppa.launchpad.net/linuxuprising/shutter/ubuntu focal/main amd64 Packages
        500 http://ppa.launchpad.net/linuxuprising/shutter/ubuntu focal/main i386 Packages
     0.94-1 -1
        100 /var/lib/dpkg/status

然后尝试安装libgnome2-perl：

libgnome2-perl : Depends: libgnomeui-0 (>= 2.22.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

尝试安装这个：

libgnomeui-0 : Depends: libgnome-keyring0 (>= 2.20.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

最后是这个

libgnome-keyring0 : Depends: libgnome-keyring-common (= 3.12.0-1build1~0ppa1~focal) but 3.12.0-1build1 is to be installed

答案1

您的输出sudo apt-cache policy shutter显示已经安装了某个版本的 shutter（/var/lib/dpkg/status实际安装或部分安装的版本），因此可能由于依赖关系中断而存在更新问题。

在这种情况下，我会尝试先删除有问题的软件包，然后重新安装，首先执行apt-get remove shutter，然后执行dpkg -P shutter，也许用--force-depends，然后是apt-get -f install。仔细观察最后一个命令的作用，因为它往往会删除其他也是问题一部分的软件包 - 有时甚至更多。

在我的系统上，刚刚从 18.04 升级到 20.04 并且不再安装快门，以下三行足以重新安装快门（可能在此期间修复了某些问题...）：

sudo add-apt-repository ppa:linuxuprising/shutter
sudo apt-get update
sudo apt-get install shutter
