我知道它是 sudo yum downgrade <package_name>-<version_info>
但总是找不到包。
例如
sudo yum --showduplicates list java-1.7.0-openjdk
Installed Packages

1:1.7.0.201-2.6.16.0.el6_10 是我想要的版本
然后我发出
sudo yum downgrade java-1.7.0-openjdk.x86_64-1:1.7.0.201-2.6.16.0.el6_10
No package java-1.7.0-openjdk.x86_64-1:1.7.0.201-2.6.16.0.el6_10 available.
Nothing to do
我试过
sudo yum downgrade java-1.7.0-openjdk-1:1.7.0.201-2.6.16.0.el6_10
No package java-1.7.0-openjdk-1:1.7.0.201-2.6.16.0.el6_10 available.
Nothing to do
有人可以帮忙吗？？？
