[Discuss] MariaDB/MySQL & dnf repository

[R. Potter]

I am assuming rpm -e <package name> is a valid way to erase or remove 
the RPM but even that does not seem to work. It's really weird. If I 
use "rpm -e" along with one of the .rpo files in the "yum.repos.d" 
directory I am told the rpm is not installed. Same if I use the name of 
the installation file. It's very interesting and annoying. You can't 
delete the files via GUI as the option is preyed out when you right 
click on one of the files. In the end I used the "rm" command which 
finally let me remove the repo's so I still got them out but it has 
certainly been a learning experience. I still am not sure how to 
address my desire for MySQL Workbench while still using MariaDB. In the 
end I might just have to go back to MySQL entirely. :(
