前言 前幾天，看到Ubuntu 18.04出一段時間了，看是時機成熟了。 所以就把自己平常工作在用的ThinkPad筆電從Ubuntu 16.04升級到Ubuntu 18.04了。 當然，中途有遇到一些情況，讓升級的程序跟步驟變得有些複雜，所以這篇文章，就是在紀錄有關於升級的過程中遇到的問題提供日後大家做參考。 前置動作 當然，需要有一台Ubuntu 16.04主機，不然要怎麼升級成18.04 如果怕升級上去之後，發生一些無法預期的事情，則可以先備份，備份工具可以使用「CloneZilla」進行備份。 升級做法 先依照下面的指令去安裝所有套件的最新版本。 12345sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade 接著按照下面的指令去檢查可以升級的版本 1sudo do-release-upgrade -c 那麼，就可以找到「Ubuntu 18.04」的發行版本
