GnuTLS 接收错误 (-110)：TLS 连接未正确终止
GnuTLS recv error (-110): The TLS connection was non-properly terminated
我准备通过 vundle 安装 vim plugin，在我设置 vimrc
之后
set nocompatible
filetype off
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'gmarik/Vundle.vim'
Plugin 'valloric/youcompleteme'
call vundle#end()
然后我输入:PluginInstall并得到错误

然后我进入目录~/.vim/bundle并执行
git clone --recursive 'https://github.com/valloric/youcompleteme.git
得到这个

正如所说，尽管出现错误，但似乎插件已下载。但实际上我找不到youcompleteme目录。
我也试试
git clone --recursive 'git@github.com:Valloric/YouCompleteMe.git' '~/.vim/bundle/youcompleteme'
得到这个
Cloning into '~/.vim/bundle/youcompleteme'...
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.
那么如何解决呢？
So how to solve this?
通过检查这些错误在接下来的几个小时内是否仍然存在。

这可能是他们问题的副作用。
另一种方法是确保您使用的是最新的 Git 版本，OP 通过重新编译 Git。
重新编译安装git终于解决了，步骤如下：
sudo apt-get install build-essential fakeroot dpkg-dev -y
sudo apt-get build-dep git -y
sudo apt-get install libcurl4-openssl-dev -y
cd ~
mkdir source-git
cd source-git/

sed -i -- '/TEST\s*=\s*test/d' ./debian/rules
dpkg-buildpackage -rfakeroot -b -uc -us
sudo dpkg -i ../git_*ubuntu*.deb
不使用-y也可以，-y只是为了跳过输入y。结果是：

出于某种原因 'git pull' 一遍又一遍地发出此消息，但 'git pull origin master' 有效
对于 windows 10 wsl2 可能遇到以下问题的任何人，可以通过以下参考进行修复：
fakeroot, while creating message channels: Function not implemented
This may be due to a lack of SYSV IPC support.
https://github.com/microsoft/WSL/issues/2465#issuecomment-377583291
sudo update-alternatives --set fakeroot /usr/bin/fakeroot-tcp
当 运行 来自 Visual Studio 的 CMake 和 Ubuntu 18.04 的 WSL 时，我找到了另一种解决此问题的方法。
我在这里找到了将 GIT 升级到最新版本的另一种方法：https://itsfoss.com/install-git-ubuntu/
sudo add-apt-repository ppa:git-core/ppa
sudo apt update
sudo apt install git
即使我们在升级后仍然有 GnuTLS recv 错误 (-110)，GIT 操作不会再失败。
这里有一种更 up-to-date 的方法。我在 Win10 上的 WSL2 上使用 Ubuntu 20.04。
sudo apt remove git -y
sudo apt update && sudo apt upgrade

sudo apt install build-essential autoconf dh-autoreconf libcurl4-openssl-dev \
tcl-dev gettext asciidoc docbook2x install-info \
