回滚单声道4.0.1到3.12.0

Question

所以,我们的单声道从3.12.0更新到4.0.1并且导致nunit出现了一堆问题,如下所示:升级到运行NUnit测试的Mono 4后的新SIGABRT虽然升级到4.1.0快照修复了这些问题,但它还没有已正式发布,我们不想使用它.相反,我们想降级回3.12.0,但似乎我甚至不能这样做.跑步apt-cache showpkg mono-complete只给我以下选项

matt@matt-T420:~/vw3$ apt-cache showpkg mono-complete

但是,如果我浏览http://origin-download.mono-project.com/repo/debian/dists/wheezy/snapshots/3.12.0/我可以看到包但我不知道如何将它添加到我的回购清单.我不知道如何修改echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list到3.12.0文件夹的pint.

我基本上只想吹掉单声道4.0,重新安装3.12.0,然后在那个版本固定/保持它.有人可以帮忙吗？

Answer 1

首先删除mono 4.0.1

sudo apt-get remove mono-complete

sudo apt-get purge mono-complete

sudo apt-get autoremove

经过几次尝试,我修改了这样的回购,这似乎有效:

echo "deb http://download.mono-project.com/repo/debian wheezy/snapshots/3.12.0 main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list

然后跑了:

sudo apt-get update

sudo apt-get install mono-complete

mono --version

我现在正在运行3.12
