当我安装Heroku时,我的包管理器坏了

sudo apt-get install <anything>
 
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/toolbelt.heroku.com_ubuntu_._en
E: The package lists or status file could not be parsed or opened.

我接下来要对此进行故障排除的步骤是什么？

更新：我尝试重新安装并获得下面的输出.它似乎安装了,但是当我从命令行尝试heroku时,我得不到命令：heroku.安装命令在[等待标题]上挂了很长时间.

基于这些错误消息,我的下一步是什么？

heroku-toolbelt is already the newest version.

以下将解决此错误：
