Ubuntu 18.04中的读行库问题

Question

在尝试运行安装Slack所需的sudo apt install debsig-verify时，我收到了以下错误消息：

You might want to run 'apt --fix-broken install' to correct these.   
The following packages have unmet dependencies:
libreadline-dev:i386 :
  Depends: libreadline7:i386 (= 7.0-3) but 7.0-0ubuntu2 is to be
installed
  Depends: libtinfo-dev:i386 but it is not going to be installed  libreadline7 : 
  Breaks: libreadline7:i386 (!= 7.0-3) but 7.0-0ubuntu2 is to be installed  \
libreadline7:i386 : 
  Breaks: libreadline7 (!= 7.0-0ubuntu2) but 7.0-3 is to be installed`

当我尝试sudo apt --fix-broken install时，我得到了以下结果：

自从我从上一个版本更新以来，我已经使用了18.04。也许这就是为什么添加了与18.04不兼容的东西。

sudo apt-get remove libreadline7 -a=i386的结果：

sudo apt-get remove readline7:i386的结果：

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution)

我还得到了另一个关于读行依赖的错误。我应该把它贴在这里吗？

Answer 1

移除导致未满足的依赖项错误的libreadline7 7:i 386。卸载libreadline7 7:i 386也将解决trying to overwrite错误。然后安装snap包，它作为一个独立的包不会造成任何额外的包管理问题，或者需要任何附加的依赖包。

sudo apt --fix-broken install  
sudo apt remove libreadline-dev:i386 libreadline7:i386  

Slack是Ubuntu18.10中的本机snap包。要在所有当前支持的Ubuntu版本中安装Slack，请打开终端并键入：

sudo snap install slack --classic  

此命令将安装最新的稳定版本的Slack，如果有更新，它也将自动更新。

要启动Slack，请单击Dash中的图标或从终端运行以下命令：

snap run slack  

Slack有一个免费的版本，供小团队或任何想要在无限制的时间内尝试Slack的人使用。
