紅寶石在rails上手動卸載

Question

我在ubunty中卸載ruby有很大的問題。 我下面https://stackoverflow.com/a/9618017/1796624，當我嘗試

aptitude purge <package name> 

我得到：

E: I wasn't able to locate a file for the ttf-mscorefonts-installer package. This might mean you need to manually fix this package. 
E: I wasn't able to locate a file for the ttf-mscorefonts-installer package. This might mean you need to manually fix this package. 
E: Internal error: couldn't generate list of packages to download 

如何完全刪除軌和紅寶石，我在哪裏可以找到TTF-mscorefonts安裝程序包，現在手動修理它 ？

Answer 1

ttf-mscorefonts-installer - 是一個用於安裝Microsoft TrueType字體的軟件包，該軟件包對rails沒有影響。
apt-get實用程序存在問題。
