2017-08-02 04:51:40 -0500 answered a question Unable to install openstack [ERROR : Failed to run remote script]

I was able to resolve it by adding proxy details to yum.conf file. Proxy=http://ipaddress:portnum

2017-08-01 21:50:32 -0500 asked a question Unable to install openstack [ERROR : Failed to run remote script]

I have installed Centos 7 in virtual box. Proxy sits between the (host and guest OS) to connect to internet. I am able to access Internet from the guest machine,, and all commands through command line like "yum", is also working. But when I install packstack and run "Packstack --allinone" command, I ended up getting the following error.

Any help will be much appreciated.

[root@centos ~]# packstack --allinone Welcome to the Packstack setup utility

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
