Docker Yum install RPM packet Error Rpmdb checksum is INVALID:DCDPT (pkg checksums): ...

Today, in the use of dockerfile to make Docker mirror, suddenly found that can run "run yum install-y sudo" Suddenly ran an error, the following errors:

Rpmdb Checksum is INVALID:DCDPT (pkg checksums): sudo.x86_64 0:1.8.6p3-29.el6_9-u the

command '/bin/sh-c yum L-y sudo ' returned a non-zero code:1

The underlying mirror used in my dockerfile is "gpmidi/centos-6.5". Research on a circle to find someone said that the RPM database damage needs to be rebuilt. Therefore, it is necessary to "yum install ..." Pre-use "RPM–REBUILDDB" to rebuild the database. Like what:

RUN rpm--rebuilddb && yum install-y sudo ...

Found in my environment sometimes if there are multiple "RUN yum install-y ..." directive, you need to add "RPM–REBUILDDB" before each bar.
