如何清理Ubuntu系統中軟體包

如果你頻繁的在你的系統中安裝/解除安裝，那麼不時的清理一下你的系統是十分必要的。

在Ubuntu終端中執行如下命令：

sudo apt-get autoremove

螢幕輸出是這個樣子的：

Reading package lists… Done
Building dependency tree
Reading state information… Done
The following packages were automatically installed and are no longer required:
libcommoncpp2-1.5.3-0
The following packages will be REMOVED
libcommoncpp2-1.5.3-0
0 upgraded, 0 newly installed, 1 to remove and 29 not upgraded.
Need to get 0B of archives.
After unpacking 688kB disk space will be freed.
Do you want to continue [Y/n]?

輸入“Y”就可以刪除這些包。

英文原文:

It’s worthwhile to do this every now again again on your ubuntu box when you’ve been installing and uninstalling new apps. This will go through and check which packages have been installed that are no longer needed. It will then remove them for you

sudo apt-get autoremove

Output looks like below
