Couldn't open file/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 problem solving,

When using yum install, occasionally encounter this error: Couldn't open file/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

This is because the following GPG key is listed in the configuration file of yum repository in your/etc/yum. repos. d directory:

Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

This configuration tells YUM that the GPG key of the repository exists on the disk. When YUM cannot find this gpg key in the path/etc/pki/rpm-GPG, the above error will be reported.

Solution:

Https://archive.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-7 for cd/etc/pki/rpm-gpgwget

Then run the yum command again. Of course, some packages can only be installed after epel is installed. How to install epel is: yum install-y epel-release
