Re^6: When i am running one of my perl script. It is getting an error like this.

When i am doing yum install or apt install i am getting an error like this so i will not able to install it on my pc

yum install libxml2 libxml2-devel
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7S
+erver&arch=x86_64&repo=os&infra=$infra error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown e
+rror"


 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point th
+e only
 safe thing yum can do is fail. There are a few ways to work "fix" thi
+s:

     1. Contact the upstream for the repository and get them to fix th
+e 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 def
+ault. Yum
        will then just ignore the repository until you permanently ena
+ble 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 unava
+ilable.
        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 oft
+en a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavai
+lable=true

You've been told several times now that you need to satisfy dependencies, yet you chose to ignore this and continue on. Starting new threads and still not telling people what goes wrong becomes boring for those responding, eventually people stop replying to such things. Nobody wants to have to keep asking you to tell us what you've tried and how it failed. `apt install libxml2 libxml2-dev -bash: apt: command not found` [download] The instructions given to you were '`yum install libxml2 libxml2-devel` or `apt install libxml2 libxml2-dev`, or whatever your OS package manager is.', you only need to use the package manager your OS uses, but since you didn't bother to tell us which OS that was..... `yum install libxml2 libxml2-devel Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7S +erver&arch=x86_64&repo=os&infra=$infra error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown e +rror"` [download] Either find out how to configure your system properly, or speak to the systems administrator.

The error message is `Could not resolve host: mirrorlist.centos.org; Unknown error` [download] This means that your machine has a network problem. Consider resolving that problem first.	[reply] [d/l]

"Could not resolve host: mirrorlist.centos.org; Unknown error" Your DNS resolution is failing. Contact your systems administrator. 🦛	[reply]
