Summary0014860: yum ignore skip_if_unavailable=1 option
Descriptionyum update ignores skip_if_unavailable option in .repo file, and failes.

Symptoms:
yum update
Loaded plugins: fastestmirror, ovl
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://XXXXXXXXXx.txt error was
14: curl#6 - "Could not resolve host: asdasdasdasdasdXXXXXXXXXx; Name or service not known"


 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:

..........
Cannot find a valid baseurl for repo: XXXXXXXXXx
Steps To Reproducedocker pull centos:7

docker run -v /etc/localtime:/etc/localtime:ro --hostname=docker-quick --ulimit nofile=4096:8192 --cpus=4 -ti centos:7 /bin/bash
# inside docker
# create repo exmple :
$ cat /etc/yum.repos.d/1.repo
[xxxx-test]
name=xxxx-test
mirrorlist=http://asdasdasdasdXXX.com/security.txt
enabled=1
gpgcheck=0
skip_if_unavailable=1

# remove all repos except fake one :
$ mv /etc/yum.repos.d/CentOS* ~/
# run update

 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: xxxx-test
Exit=1
