Hi,
My name's Ilan and I'm a new user.
I installed CentOS 7 64 bit with VMware Player as guest and try 'yum
update' to get newest application and get error as mentioned below. It seem
me the installation determines the IP address as loopback and I don't know
how enable it as real/virtual.
I copy & paste the findings from Linux and Windows.
Any help will be blessed.
Regards,
Ilan.
[root at localhost Desktop]# yum update
Loaded plugins: fastestmirror, langpacks
Could not retrieve mirrorlist
http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os 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. Disable the repository, 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>
4. 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
