not able to update yum. gives error no 14- HTTP error 404
Posted: 2018/07/20 04:30:24
i am trying install openstack on centOS 7.
I was able to install "sudo yum install -y centos-release-openstack-ocata". Then i tried to update packages on centos and it giving me above mentioned error.
I can ping internet/google.com. I am not using any proxy setting.
**************i get below message**********************
https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.
One of the configured repositories failed (CentOS-7 - QEMU EV),
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=centos-qemu-ev ...
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 centos-qemu-ev
or
subscription-manager repos --disable=centos-qemu-ev
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=centos-qemu-ev.skip_if_unavailable=true
failure: repodata/repomd.xml from centos-qemu-ev: [Errno 256] No more mirrors to try.
http://mirror.centos.org/altarch/7/virt ... repomd.xml: [Errno 14] HTTP Error 404 - Not Found
How to recover from this?
