yum update - 14: PYCURL ERROR 7 - Failed to connect

Post by skilet » 2019/04/26 14:09:05

Hi People

when i want use yum update i get next error:

Code: Select all

[root@]# yum update

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was

#  This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
#  It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).

That's telling you 2 things: first that your ipv6 networking is broken as it cannot reach mirrorlist.centos.org over it. Second, it's telling you that your ipv4 network is broken too since it tries that first, fails silently then moves on and tries to use ipv6 and gets the visible error that you see there.

So you need to fix your ipv4 network so that you can reach the internet. You should also fix your ipv6 connectivity as that is also broken at the moment.

Try using curl -4 "http://mirrorlist.centos.org/?release=6 ... nfra=stock" to retrieve the mirror list output. The quotes round the url are required and necessary. Use what that says to debug the real problem with your network now.

For extra points, use -v:

Code: Select all

curl -4v "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock"
This will show the reply headers as well, if you get that far with your request. Maybe you won't.

I'd be pretty sure that you have a firewall problem. Someone has blocked port 80 which is why you can ping those ip addresses (which uses icmp) and yet you cannot connect over tcp port 80.

Talk to your network/security department, whichever one maintains the firewall.

You Right the firewall is a problem.
