I see similar questions about this from over a year ago which suggest modifying /etc/yum/vars/releasever or removing /var/cache/dnf, but that releasever file doesn't exist in this image and removing that dnf cache does not help.Īny help to resolve this would be appreciated. Note: To install an edge package, change the word stable in the URL to edge. deb file for the Docker version you want to install. I'm not sure whether this is specific to the docker image or is a broader centos:8 issue. 1.Go to choose your Ubuntu version, browse to pool/stable/ and choose amd64, armhf, ppc64el, or s390x. $ docker run -it -init -cap-add=SYS_PTRACE -network=host centos:8 /]# yum clean allįailed to set locale, defaulting to C.UTF-8ĬentOS Linux 8 - AppStream 988 B/s | 38 B 00:00Įrror: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
dnf install docker-ce docker-ce-cli containerd.
dnf config-manager -add-repo Install the Docker package. All yum commands fail with the error message Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist. Docker installation on CentOS 8 To install and always update Docker to the latest version, add the developer repository to the system. With the latest centos:8 docker.hub image I cannot run yum.
