Get Claymore Working on Linux (Ubuntu)

This worked for me.  I was getting a libcurl3 error.  New versions of Ubuntu 18.04 use libcurl4, this does not work for Claymore.  I uninstalled libcurl4 and installed libcurl3.  Now there may be programs dependant on libcurl4 however this machines sole purpose is to mine so removing 4 for 3 was not an issue.

sudo apt-get remove libcurl4
sudo apt-get install libcurl3

AMD drivers and Nvidia drivers are available for download through repositories.
