我从软件中心下载并尝试从命令行安装 Ubuntu 20.04，但出现相同的错误。它在另一个 SSD 上的 Ubuntu 安装上运行良好，但在这个较新的 SSD 上的新安装中却无法运行。
我看到了这一点：https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=944875
它说应该已经修复了。我该怎么办？卸载时，我按照以下说明操作： https://www.thelinuxfaq.com/ubuntu/ubuntu-17-04-zesty-/calibre?type=uninstall
安装后我跑了
sudo apt-get update
sudo apt update
sudo apt-get upgrade
sudo apt upgrade
