Regarding yum autoupdate errors: my thanks to Alec Habig, Alan Bartlett and Akemi Yagi for giving me three good options. I chose Akemi’s: > EPEL had a version of libgpod that was newer than the version in > RHEL 7.4. This causes an update error. So, if you have already > installed the one from EPEL, just 'yum downgrade' the package. This worked flawlessly: # yum downgrade libgpod # yum update Steve ------------------------------------------------------------------------ Stephen L.
