我知道那条消息之后的含义sudo apt update，并且它通常是有用且无害的。
但在过去某个时候，在安装不同的系统时，它建议删除很多程序，在我删除它们之后，我什么也没有了。操作系统。
这里也是这样吗？
以下软件包是否至关重要或者我可以安全地删除它们？

Use 'sudo apt autoremove' to remove them.
我在使用 Ubuntu Budgie 16.04，64位。
编辑/更新：
sudo apt update如果单独运行则不提供该列表；在添加 ppa 后运行则提供该列表sudo apt upgrade已提供清单删除所有第三方 ppa-s，列表仍然出现（仅在
sudo apt update单独之后出现）
答案1
正如@dedunumax 的评论所说，大多数软件包都是 32 位的。
其余的都不重要。
将其移除sudo apt autoremove是一种安全的方法。
（但我会重新安装一些被删除的，比如python-dbus，这对于讨论的目的似乎很有用这里。
