Error: GPG check FAILED
The command '/bin/sh -c dnf -y --enablerepo=PowerTools install boost-static' returned a non-zero code: 1
解决方法：
添加--nogpgcheck参数
FROM centos:8
RUN yum install -y \
openssl-devel \
bc \
cmake \
elfutils-libelf-devel
RUN dnf -y --enablerepo=PowerTools --nogpgcheck install boost-static
RUN yum -y groupinstall 'Development Tools' --nogpgcheck
方法二：（未验证）
first cd to:
$ cd /etc/pki/rpm-gpg
Then do a wget command, here's an example:
$ wget -O http://yum.theforeman.org/releases/1.8/RPM-GPG-KEY-foreman
then import it into rpm db like this:
$ rpm --import RPM-GPG-KEY-foreman
You can list all the imported keys like this:
$ rpm -qa gpg*
then to check it have worked, you can do:
$ rpm -qi gpg-pubkey-225c9b71-54fda121 Name : gpg-pubkey Relocations: (not relocatable) Version : 225c9b71 Vendor: (none) Release : 54fda121 Build Date: Wed 28 Oct 2015 11:41:38 AM GMT Install Date: Wed 28 Oct 2015 11:41:38 AM GMT Build Host: localhost Group : Public Keys Source RPM: (none) Size : 0 License: pubkey Signature : (none) Summary : gpg(Foreman Release Signing Key (1.8) <[email protected]>) Description : -----BEGIN PGP PUBLIC KEY BLOCK-----
