Yum Error – ImportError: No module named yummain
You may see an error like the below when attempting to see if a certain package is installed using the yum package manager. Yum is the default package manager on RedHat Linux and CentOS Linux. Using the “yum list *SOMETEXT*” command will list all packages that contain “sometext” or you could use “yum list sometext” which will list a package specifically called “sometext”. Below you can see an attempt to list the “git” package on a CentOS server however an error was returned.
