An error occurred while installing the source package centos package XXX. rpm is not signed

Using the yum command in the centos system is indeed a pleasant task, but there are also various problems in some cases.

One we met today is very tricky.

Yum install XXX. rpm

Warning:

Package XXX. rpm is not signed

Google, the solution is
1. Modify yum. conf

Path:/etc/yum. conf

Find gpgcheck = 1

Change it to 0: gpgcheck = 0

2. Modify/etc/yum. Repos. d/utterramblings. repo.

Find gpgcheck = 1

Change it to 0: gpgcheck = 0

However, after these two files were changed, they were still useless. At this time, I found a post and suddenly realized that

Just add -- nogpgcheck to the end. The format is as follows:

Yum install * rpm -- nogpgcheck
