RT.因为online16的机器只能使用centos7,fuc*k,只好在某工上默默练习centos7,真是无力吐槽,防火墙改的像家用机....
## 在新机器上执行`yum update -y`出现以下错误:
```bash
Loaded plugins: fastestmirror, langpacks
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
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=.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64`
```
大婶,求指招,应该有人遇到了吧..应该不会有人像我这样只会玩centos6.7吧.
