我今天刚刚从 18.04 升级到 20.04，我不确定升级过程中是否有错误。由于这个库，我无法升级库并将 do-release-upgrade 升级到较新的版本。
对于未升级并允许我继续的库，我在下面包含了一些输出：

我可以简单地删除该库吗？欢迎提供任何建议。
答案1
在删除 mesa-opencl-icd 之前，请先运行模拟程序，看看删除此包后会发生什么情况（无需实际删除任何内容）。请注意，此命令不应以 root 身份运行，也不应以 开头，sudo因为这只是一个模拟程序。
apt remove --simulate mesa-opencl-icd
如果你无法删除 mesa-opencl-icd，你可以简单地使用以下命令升级它sudo apt install mesa-opencl-icd
