小编RE6*_*60K的帖子

从 Ubuntu 16.04 升级后，此选项似乎已消失。我尝试安装，nautilus-open-terminal但无法找到 18.04 的软件包。还尝试安装nautilus-actions给出：

Package nautilus-actions is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

如何解决这个问题？
