CentOS can't update.

hack3rcon · 07-01-2018, 02:36 AM

Hello.
I'm using CentOS 7 x86_64 and used "yum update" but my system rebooted. Yum installed the new kernel but it can't load and show me a panic error. when I boot my system using the old kernel and run "yum install packagename" then it can't work. For example:

Code:

$ sudo yum install iputils
Loaded plugins: fastestmirror, langpacks

Code:

Transaction check error:
  package iputils-20160308-10.el7.x86_64 is already installed

Sometimes a re-start may resolve confusion.

Thank you.

What you're saying makes very little sense; you don't post the "panic error", by which, I assume you actually mean "kernel panic". So how do you expect us to be able to tell you why it "can't load" if you don't post it ??

You're own error message from yum is clearly telling you why "yum install <package name>" "can't work";

Code:

Transaction check error:
  package iputils-20160308-10.el7.x86_64 is already installed

It's clearly telling you that it's ALREADY installed. Not sure how you don't understand that ? That's why it "can't work".

The "kernel" package from the CentOS official repo is verified TO work with CentOS. If you want the very latest kernel for CentOS, you need to add the "elrepo" software repo to yum's repo list. If you don't, you will not get the very latest kernel for CentOS period.

If it is already installed why yum download it but never install it?

Did you actually READ post #3 OR you're own error message ??

yum did not download it. You asked for an install of an already-installed package, yum detected that it was already installed, told you so, and quit.

Note that yum switched to update:

Code:

Updating:
 iputils                            x86_64                            20160308-10.el7                               base                            148 k

so try

Code:

sudo yum update iputils

An aside: You mention something about "installing new kernel" but the code you posted has nothing to do with the kernel...

Code:

yum info iputils
...
Name        : iputils
Arch        : x86_64
Version     : 20160308
Release     : 10.el7
Size        : 335 k
Repo        : installed
From repo   : anaconda
Summary     : Network monitoring tools including ping
URL         : https://github.com/iputils/iputils
License     : BSD and GPLv2+
Description : The iputils package contains basic utilities for monitoring a network,
            : including ping. The ping command sends a series of ICMP protocol
            : ECHO_REQUEST packets to a specified network host to discover whether
            : the target machine is alive and receiving network traffic.

...and based on what I see on my system, 20160308 is the latest version of iputils.

Suggest careful review of

Code:

yum --help

or

Code:

man yum
