我想将Ubuntu从19.04升级到20.04，但是直到我更新所有软件包后，才有可能。

我做错什么了吗？可能是我不明白为什么无法从Ubuntu 19.04迁移到Ubuntu 20.04的真正原因。有任何想法吗？
答案 0 :(得分：1)
我刚刚在 Ubuntu 20.04 上尝试升级我的 cuda 时遇到了同样的问题。
sudo apt upgrade 只会添加升级/添加包，永远不会删除包。
但是，升级 cuda 通常需要删除一堆旧的 nvidia 驱动程序包并用新包替换它们。
sudo apt full-upgrade 可以在需要更新软件包时删除软件包：
full-upgrade (apt-get(8))
full-upgrade 执行升级功能，但如果需要将系统整体升级，则会删除当前安装的软件包。
（来自man apt https://manpages.ubuntu.com/manpages/focal/man8/apt.8.html）
不幸的是，至少对于 apt 版本 2.0.5，sudo apt full-upgrade 仍然不想更新 cuda。
Debian buster upgrade notes 建议当 apt full-upgrade 不起作用时，您应该在受影响的包上手动运行 install：sudo apt install cuda，或者使用 aptitude更强大的包解析算法：
我可以确认使用 sudo aptitude full-upgrade 或 sudo apt install cuda 都有效，请参阅以下输出（为简洁起见进行了编辑）

aptitude 不是默认安装的，因此您可能需要先运行 sudo apt install aptitude 来安装它。请记住，虽然 full-upgrade 通常是安全的，但由于它确实会删除软件包，因此它偶尔会破坏您的系统。
