我已经从 Ubuntu 16.04 更新到20.04。这样做时升级失败了，我最终重新安装了 20.04。幸运的是，我在另一个驱动器上有我的主文件夹，所以它被保存了。还有很多东西需要恢复。我坚持的最后一项是让我的AMD Radeon 580 GPU工作。AMD 不支持 16.04 之后的 Ubuntu 驱动程序。我尝试从下面的页面安装OPENCL。而且，我希望我安装了正确的软件。

同时遵循此视频的建议：https : //www.youtube.com/watch?v=efKjfBkjPlM
目的是在我的计算机空闲时使用xmrig程序进行一些 GPU 加密挖掘。
为了检查是否成功完成，我有 rocminfo 和 clinfo 命令。
rocminfo 的结果是：
joe@joeslinux:~$ /opt/rocm/bin/rocminfo

clinfo 是个陌生人。运行 clinfo，我得到：
joe@joeslinux:~$ clinfo
terminate called after throwing an instance of 'cl::Error'
what(): clGetPlatformIDs
Aborted (core dumped)
从目录运行它得到了一个不同的错误：
joe@joeslinux:~$ /opt/rocm/opencl/bin/x86_64/clinfo
ERROR: clGetPlatformIDs(-1001)
从目录中使用 sudo 运行它得到了似乎是有效的输出。joe@joeslinux:~$ sudo /opt/rocm/opencl/bin/x86_64/clinfo

clinfo 及其文件夹归 1001 所有。我知道这意味着没有所有者 1001。
drwxrwxr-x 5 1001 1001 4096 May 17 22:28 opencl
我将所有者更改为root。然后我再次运行 clinfo 命令，但这没有任何区别。
我试图运行的程序是 xmrig。
这是错误行：
./xmrig ...
* OPENCL disabled (failed to load OpenCL runtime)
另请注意，我之前没有运行过这个 xmrig 挖矿程序，那是在 16.04 上。当时我使用了不同的矿机。
先感谢您。
我终于找到了有效的说明！
我尝试从网上找到的许多说明中安装 OpenCl。大多数是沮丧的练习。这是对我有用的那个。https://gist.github.com/kytulendu/3351b5d0b4f947e19df36b1ea3c95cbe
