我想在 Ubuntu 19.04 上安装“qt5-default”
从...开始
sudo apt-get install qt5-default
我得到“qt5-default：依赖：qtbase5-dev但是它不会被安装”
在
sudo apt-get install qtbase5-dev
我得到“qtbase5-dev：依赖：libvulkan-dev，但它不会被安装”
在
sudo apt-get install libvulkan-dev
我得到“libvulkan-dev：依赖：libvulkan1（= 1.1.101.0-2）但需要安装 1.1.114.0-1~gpu18.04.1”
我不知道现在该怎么办
这台电脑运行的是 gtx1080ti，我为其安装了 CUDA，所以我不确定如何将 libvulkan1 (= 1.1.101.0-2) 转换为 1.1.114.0-1~gpu18.04.1，以及这样做是否会破坏任何东西。此外，我也不确定我解决问题的尝试是否正确。我不是经验丰富的 Ubuntu 用户。

在 18.04 上，您从 ppa 获得了更高版本的 libvulkan1，并且在升级之前没有使用 ppa-purge。因此最简单的方法是将 ppa 重新添加到 disco 并更新到 19.04 的 ppa libvulkan1 包（以及任何其他已安装的 ppa 包），然后使用 ppa-purge 降级到 disco 包。然后您应该升级到 19.10，因为 19.04 是 EOL
