请帮助我，因为我陷入困境
答案1
我看到了来自三个不同版本的源代码，包括一个已经过期的版本。还有许多重复的源代码。还有不少于五个 PPA 和其他非 Ubuntu 源代码。这证明了 Debian 和 Ubuntu 开发人员的技能，这个拼凑起来的怪物完全可以胜任。
建议：备份您的数据，然后从头开始，重新安装。您从这次迭代中学到了很多东西，请将这些经验带到下一次迭代中：
- 切勿混合不同 Ubuntu 版本的源代码。
- 除非您知道如何维护 PPA 和非 Ubuntu 源，否则请避免使用它们。请记住，如果它们导致版本冲突，您可能需要删除它们（及其所有软件包）。
- 如果您想要在旧的 LTS 版本上使用较新的软件，请寻找 Snaps 而不是 PPA 或非 Ubuntu deb 源。
- 花几分钟时间学习如何管理你的资源。查看格式、每个文件的用途、每个存储库的用途、这些资源如何驱动
apt update以及如何使用输出来解决大量问题。
