如何在15.04下安装gitg 2.7版？
我更新到Ubuntu 15.04。 发布的gitg版本是3.15.1 – 在Ubuntu 14.10中它是2.7.3。
我真的很想再次安装旧版本，因为新版本非常不方便处理。 如何重新安装旧版本。 package force version未提供。
我卸载了新版本。 我从http://packages.ubuntu.com/utopic/amd64/gitg/download下载了.deb-package，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：

当我之后单击repair ，则安装版本3.15.1 。 如果我没有单击修复，则安装2.7.3（并且可以运行）。
那么，有没有更好的方法来安装旧版本的gitg？
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
并暂停：
sudo apt-mark hold gitg
整体与之相反
sudo apt-mark unhold gitg sudo apt-get upgrade
该软件包可以从https://packages.debian.org/jessie/amd64/gitg/download获得。 （如果您使用的是与amd64不同的架构，请在此处选择它。）
