最近笔记本升级到Windows 11后，利用Oralce Vagrant项目安装19.3.0企业版总是出错，错误为：

...oracle-19c-vagrant:   Installing : 2:ethtool-4.8-10.el7.x86_64                                54/55oracle-19c-vagrant:   Installing : oracle-database-preinstall-19c-1.0-3.el7.x86_64            55/55
The SSH connection was unexpectedly closed by the remote end. This
usually indicates that SSH within the guest machine was unable to
properly start up. Please boot the VM in GUI mode to check whether
it is booting properly.

目前没有找到原因，但有一个临时解决方法。

首先，修改scripts目录下的install.sh文件，将yum install -y oracle-database-preinstall-19c openssl语句移动到前面，即注释# get up to date的下方：

# get up to date
# 新的位置
yum install -y oracle-database-preinstall-19c openssl
yum upgrade -yecho 'INSTALLER: System updated'# fix locale warning
yum reinstall -y glibc-common
echo LANG=en_US.utf-8 >> /etc/environment
echo LC_ALL=en_US.utf-8 >> /etc/environmentecho 'INSTALLER: Locale set'# set system time zone
sudo timedatectl set-timezone $SYSTEM_TIMEZONE
echo "INSTALLER: System time zone set to $SYSTEM_TIMEZONE"
# 原来的位置
# yum install -y oracle-database-preinstall-19c openssl
...

然后，可以开始安装。在进行到以下界面时，界面会停住：

...oracle-19c-vagrant-ok:   Verifying  : psmisc-22.20-17.el7.x86_64                                 55/59oracle-19c-vagrant-ok:   Verifying  : libX11-common-1.6.7-4.el7_9.noarch                         56/59oracle-19c-vagrant-ok:   Verifying  : 1:quota-nls-4.01-19.el7.noarch                             57/59oracle-19c-vagrant-ok:   Verifying  : 1:openssl-1.0.2k-25.el7_9.x86_64                           58/59oracle-19c-vagrant-ok:   Verifying  : 1:openssl-libs-1.0.2k-25.el7_9.x86_64                      59/59oracle-19c-vagrant-ok:oracle-19c-vagrant-ok: Installed:oracle-19c-vagrant-ok:   oracle-database-preinstall-19c.x86_64 0:1.0-3.el7
...

此时只需要另起一个窗口，进入vagrant项目的目录，执行vagrant ssh或vagrant putty命令登录虚机，然后上面停顿的命令就可以继续了。接下来就正常安装了。

所以还是很怀疑是ssh的问题。
