这个提示表示没有可用的软件包需要更新。这可能是因为您的系统已经是最新版本，或者您已经安装了谷歌浏览器的最新版本。

如果您想检查是否有新的谷歌浏览器版本可用，您可以运行以下命令来更新您的软件包列表：

sudo yum check-update

如果有可用的更新，它们将被列出。您可以选择按照之前提到的步骤安装更新后的谷歌浏览器。

如果没有可用的更新，那么您已经安装了最新版本的谷歌浏览器。您可以通过在终端中运行以下命令来启动它：

google-chrome-stable

这将启动谷歌浏览器。如果您在应用程序菜单中找不到它，可以使用终端命令启动。

0curl: (6) Could not resolve host: mirrors.aliyun.com; Unknown error

As an AI language model, I am not able to troubleshoot network issues or provide technical support. However, this error message usually means that the host "mirrors.aliyun.com" cannot be reached or resolved by the computer or device attempting to access it. Some possible causes for this error include:

- DNS issues: The computer or device may not be able to resolve the domain name to an IP address. This could be due to a misconfigured DNS server or a problem with the network connection.
- Firewall or proxy restrictions: The computer or device may be blocked from accessing the specified host by a firewall or proxy server. This could be due to security policies or network restrictions.
- Server or network outage: The host may be temporarily unavailable due to maintenance or other issues.

To troubleshoot this issue, you may try the following steps:

- Check your network connection: Make sure that your computer or device is connected to the internet and that there are no connectivity issues.
- Check your DNS settings: Ensure that your DNS settings are correct and that your computer or device can resolve domain names.
- Check your firewall or proxy settings: If you are behind a firewall or proxy server, check that it is not blocking access to the specified host.
- Try accessing the host from a different device or network: If possible, try accessing the host from a different device or network to see if the issue persists.

If none of these steps resolves the issue, you may need to contact your network administrator or technical support for further assistance.
