最近要開始測試client安裝 ubuntu 18.04 的 ansible playbook
因為要不斷的修正，所以想到一直有在自己電腦上執行的timeshift這個軟體
可以很簡單快速的備份、恢復系統狀態
可是不知道為什麼，在ubuntu 18.04 上安裝就是會發生錯誤….
因為client 的環境都躲在proxy後面，一開始我想說直接下1
2export http_proxy=http://proxy_server:port
export https_proxy=http://proxy_server:port
然後再去依照官方的指令，新增repository就好1
sudo add-apt-repository ppa:teejee2008/ppa
結果當然不是我想的那麼簡單…
直接就跳錯誤出來了
1 | 2019-03-11 13:57:28 [mini@pc074 ~]$ sudo add-apt-repository ppa:teejee2008/ppa |
翻了一下google，有找到解法，但沒找到原因，就先這樣吧…(不求甚解)
1 | export http_proxy=http://proxy_server:port |
裝好之後，看一下怎麼執行，其實很簡單，也不用特別去指定什麼路徑1

這樣就備份完了，來測試一下備份是否正常，先隨便裝個本來沒裝的軟體1

然後還原，中間會問你要不要重新安裝 grub ，就看個人需求，我是都會讓它重新安裝一次啦
1 | 2019-03-11 14:11:53 [minion074 ~]$ sudo timeshift --restore --snapshot '2019-03-11_14-01-01' --target /dev/sda1 |
要特別注意，restore完後，會自動reboot
重新開機完成後，就入系統，執行看看 joe
1 | 2019-03-11 14:14:53 [minion@hqpc074 ~]$ joe |
可以看到，剛剛安裝的joe 又變成還沒安裝的狀態了，符合預期中的結果！
可以繼續測試playbook了！
