在Ubuntu 20.04上安装linuxuprising上的Shutter时出现的“坏包”错误

Question

04我想重新安装快门。

我遵循了在https://www.linuxuprising.com/2018/10/shutter-removed-from-ubuntu-1810-and.html上找到的指示(它也声称在20.04工作)

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

然而，Shutter仍然不会安装：

 ~  sudo apt install shutter

有什么办法让我安装它吗？

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.

试图安装这个：

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.

最后这个

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

您的sudo apt-cache policy shutter输出显示已经安装了快门的版本(/var/lib/dpkg/status是实际安装的或部分安装的)，因此由于依赖关系中断，存在/可能存在更新问题。

在这种情况下，我尝试先删除有问题的包，然后重新安装，首先执行apt-get remove shutter，然后执行dpkg -P shutter，可能是使用--force-depends，然后是apt-get -f install。仔细观察最后一个命令做什么，因为它倾向于删除其他包，这些包也是问题的一部分--有时甚至更多。

在我的系统上，刚刚从18.04升级到20.04，再也没有安装快门，以下三行就足够重新安装快门了(可能是同时修复了一些东西)：

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