这些错误信息表明,apt 在更新软件包时遇到了签名验证失败的问题。这可能是由于存储库中的 GPG 签名已过期或无法验证,或者存储库本身没有签名。
你可以尝试以下方法来解决此问题:
1. 检查你的网络连接是否正常,并确保能够访问相应的存储库。
2. 如果是第一次遇到此问题,你可以尝试更新 apt 的密钥列表。你可以使用以下命令更新密钥列表:
```
sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
```
3. 如果密钥列表无效,则需要重新导入相关存储库的 GPG 公钥。你可以通过以下命令来导入 GPG 公钥:
```
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys <KEY>
```
其中,`<KEY>` 是存储库的 GPG 公钥 ID。
4. 如果存储库没有签名,则你需要考虑使用其他可信赖的存储库或联系存储库的维护者寻求帮助。
5. 对于最后两个错误,可能是由于存储库的版本与你的 Ubuntu 版本不兼容所致。你需要检查存储库是否支持你的 Ubuntu 版本,并根据需要将其从源列表中删除。

com.mathworks.toolbox.javabuilder.MWException: An error occurred while initializing the component.
这个错误通常是由于Java Builder在初始化组件时出现问题而引起的。有几个可能的原因:
1. 缺少依赖项 - 确保您的应用程序具有所有必需的依赖项,并且它们具有正确的版本。
2. 损坏的组件 - 如果您的组件已损坏或丢失,则可能会遇到此问题。尝试重新安装组件并重新编译您的应用程序。
3. 内存不足 - 如果您的计算机没有足够的内存来运行组件,则可能会遇到此问题。尝试关闭其他应用程序或增加您的计算机的内存。
如果以上方法都不能解决问题,建议您联系组件的开发人员或制造商以获取更多帮助。
