【小技巧】Raspberry Pi 4B樹莓派 | 樹莓派apt安裝libtiff5-dev庫報錯

安裝libtiff5：

  sudo apt-get install libtiff5-dev -y

報錯如下：

The following packages have unmet dependencies:
libtiff5-dev : Depends: libjbig-dev but it is not going to be installed
Depends: libjpeg-dev
Depends: liblzma-dev but it is not going to be installed
Depends: libtiff5 (= 4.0.8-2+deb9u4) but 4.0.10-4 is to be installed
E: Unable to correct problems, you have held broken packages.

解決方案：

首先說說爲什麼會這樣，原因就是參考資料文章裏面說的這樣：" 剛安裝好樹莓派的時候，爲了更新速度快，換了國內的源，結果換！錯！了！"
只顧着按照網上的教程做，沒有考慮太多，坑太多了！

根據自己安裝的樹莓派系統版本更新源，Debian 10 Buster？ Stretch？Jessie？

deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi

deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
