I am trying to install realvnc server on my CentOS 7 VM. I've downloaded the rpm package from the official website.
I am using ESXI and nothing is or should be connected to the internet.
sudo yum install VNC-Server-6.4.0-Linux-x64.rpm it fails because it tries to connect to the internet to download packages there.
here the output:
[frodo@localhost ~]$ sudo yum install Desktop/VNC-Server-6.4.0-Linux-x64.rpm [sudo] password for frodo: Loaded plugins: fastestmirror, langpacks Examining Desktop/VNC-Server-6.4.0-Linux-x64.rpm: realvnc-vnc-server-22.214.171.124899-1.x86_64 Marking Desktop/VNC-Server-6.4.0-Linux-x64.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package realvnc-vnc-server.x86_64 0:126.96.36.199899-1 will be installed --> Processing Dependency: xterm for package: realvnc-vnc-server-188.8.131.52899-1.x86_64 Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64
