关于如何解决此问题的任何建议都将非常有帮助。
答案1
您拥有令人印象深刻的第三方 PPA 列表。这给您的系统带来了不标准的问题，因此可能无法升级。
也许清除每个 PPA，即删除 PPA 及其附带的软件，可能会将您恢复到可以再次更新的标准系统（前提是您使用 将其完全更新sudo apt full-upgrade）。然后可以在升级后添加这些。请注意，您有责任检查它是否适合新的 Ubuntu 版本。一些 PPA 继续工作，在其他情况下，新版本有专用的 PPA，在某些情况下，可能没有合适的 PPA。
不过，重新安装并重新配置系统可能同样容易。这样做的好处是，您将拥有一个干净的系统，旧的过时配置已经消失。
答案2
sudo apt-get autoremove
将删除不必要的软件包。然后使用 do-release-upgrade 命令更新到最新版本。
