我已经从更新管理器将 Ubuntu 18.04 升级到 20.04 LTS。升级后没有成功，重启后我发现系统有部分升级（一些图标来自 Ubuntu 20.04）。运行时
sudo apt--fix-broken 安装

无法解决问题。如何获得 Ubuntu 20.0 的完整安装？
答案1
首先删除有问题的对象/目录
sudo rm -rf /var/lib/dpkg/tmp.ci
然后清理下载的软件包
sudo apt-get clean
并恢复升级程序：
sudo apt-get update
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get dist-upgrade
