我已更新至 Ubuntu 15.04。gitg 的发布版本是3.15.1- 在 Ubuntu 14.10 中为 2.7.3。
我真的很想重新安装旧版本，因为新版本操作起来非常不方便。我该如何重新安装旧版本？ 中没有提供package force version。
我卸载了新版本。我从http://packages.ubuntu.com/utopic/amd64/gitg/download，但是当我尝试使用双击安装它时，安装了新版本并给出了错误：
Package operation failed
The installation or removal of a software package failed.

当我随后单击时repair，版本3.15.1就安装好了。如果我不单击修复，那么 2.7.3 就安装好了（并且可以运行）。
那么，有没有更好的方法来安装旧版本的 gitg？
答案1
打开终端并运行以下命令：
sudo dpkg -i gitg_0.2.7-3_amd64.deb
sudo apt-get remove libgit2-glib-1.0-0
并设置为保持：
sudo apt-mark hold gitg
整体反转为
sudo apt-mark unhold gitg
sudo apt-get upgrade
该软件包可以从https://packages.debian.org/jessie/amd64/gitg/download。（如果您使用的架构与 不同amd64，请选择它这里。
