Why is git submodule update failing?
提问by Octaflop
I have the following .gitmodulesfile:
我有以下 .gitmodules文件：
[submodule "web/blog"]
path = web/blog
url = git://amygdala.servebeer.com:lucky_blog.git
[submodule "web/old"]
path = web/old
url = git://amygdala.servebeer.com:old_lucky.git
When I clone the repo and run git submodule init && git submodule update(or git submodule init --update) I get the following error:
当我克隆 repo 并运行git submodule init && git submodule update（或git submodule init --update）时，出现以下错误：
Cloning into web/blog...
fatal: Unable to look up (port 9418) (Name or service not known)
Clone of 'git://amygdala.servebeer.com:lucky_blog.git' into submodule path 'web/blog' failed
I observe three things which cause some concern:
我观察到三件事引起了一些关注：
- The second
.gitmodulesentry (web/old) is cloned just fine, with no issues. - There appears to be an extra space in the error message, where I think git would normally list the hostname it fails to look up (right before the port number listing in the error listed above).
git clone git://amygdala.servebeer.com:lucky_blog.gitworks just fine.
- 第二个
.gitmodules条目（网络/旧）克隆得很好，没有问题。 - 错误消息中似乎有一个额外的空格，我认为 git 通常会列出它无法查找的主机名（就在上面列出的错误中列出的端口号之前）。
git clone git://amygdala.servebeer.com:lucky_blog.git工作得很好。
What is wrong with this repo? Is this an error with git or did I screw something up when setting up the repo?
这个回购有什么问题？这是 git 的错误还是我在设置 repo 时搞砸了什么？
EditHere's my git config for reference:
编辑这是我的 git 配置以供参考：
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:luckybead.git
[branch "master"]
remote = origin
merge = refs/heads/master
[submodule "web/blog"]
url = git://amygdala.servebeer.com:lucky_blog.git
[submodule "web/old"]
url = git://amygdala.servebeer.com:old_lucky.git

You have the format of your git URLsslightly wrong - you should separate the host from the path with /rather than :. Try changing the URLs to:
您的 git URL 格式略有错误 - 您应该将主机与路径分开，/而不是:. 尝试将 URL 更改为：
git://amygdala.servebeer.com/lucky_blog.git
git://amygdala.servebeer.com/old_lucky.git
You will not only need to commit those changes to .gitmodules, but also change the config with:
您不仅需要将这些更改提交到.gitmodules，还需要使用以下内容更改配置：
$ git config submodule.web/blog.url git://amygdala.servebeer.com/lucky_blog.git
$ git config submodule.web/old.url git://amygdala.servebeer.com/old_blog.git
... and to make sure that the submodules are re-cloned, remove them and try the git submodule updateagain.
...并确保子模块被重新克隆，删除它们并重试git submodule update。
