安装宝塔提示这个错误、一般是DNS问题、或者更换个安装节点

At this point the onlysafe thing yum can do is fail. There are a few ways to work "fix" this : Contact the upstream for the repository ã 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 thepackages for the previous di stribution release still work) 3. Disable the repository. sO yum won't use it by default. Yum will then. just ignore the repository until you pe rmanently enable it again or use --enablerepo for temporary usage : yum configmanager --di.disableConfigure the failing repository to be skipped, if it is unavailable.Note that yum will try to contact the repo. when. it runs most conmands, o will have to try and fail each time (and thus. yum will be be much J slower) . If it is a very temporary problem though, this is often a nicecompromise: yum config-manager -- save -- setopt=crepoid> .skip_ if_ unavai lable=t rue Cannot find a valid baseurl for repo: base/7/x86_ 64 I[rootelocalhost ~]#[ rootGlocalhost ~
