这个问题的原因是RPM包管理器在安装MySQL 5.7 Community Server时检测到了GPG密钥错误。要解决这个问题,你可以尝试以下几个步骤:
1. 首先,你需要确认RPM包管理器配置文件中的密钥URL是否正确。可以通过编辑 `/etc/yum.repos.d/mysql-community.repo` 文件来检查。确保密钥URL是指向正确的位置。
2. 如果你确认密钥URL配置正确,那么可能是因为你的密钥已过期或损坏。你可以尝试重新导入正确的密钥。可以使用以下命令重新导入密钥:
```
sudo rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql
```
3. 如果上述步骤仍然无法解决问题,你可以尝试清除Yum缓存并重新安装MySQL 5.7 Community Server。执行以下命令清除缓存:
```
sudo yum clean all
```
然后再次尝试安装MySQL 5.7 Community Server。
希望以上步骤能帮助你解决问题。如果问题仍然存在,请提供更多详细信息,以便我能够更好地帮助你。

Could not transfer artifact mysql:mysql-connector-java:pom:unknown from/to central
This error message usually occurs when Maven is unable to download an artifact from the central repository due to network connectivity issues or server problems.
You can try the following steps to resolve this issue:
1. Check your internet connection and make sure it is stable.
2. Clear your local Maven repository and try downloading the artifact again. You can do this by deleting the contents of the ".m2/repository" folder in your home directory.
3. Check if the artifact exists in any other repositories that you have configured in your project's pom.xml file.
4. If none of the above steps work, you can try adding the central repository to your project's pom.xml file explicitly:
```
<repositories>
<repository>
<id>central</id>
<url>https://repo.maven.apache.org/maven2</url>
</repository>
</repositories>
```
This will ensure that Maven always tries to download artifacts from the central repository.
