Update Centos 7 failed!

[martinmin]

My centos version:

Code: Select all

$ lsb_release -d
Description:    CentOS Linux release 7.6.1810 (Core) 

I had problems in installing python3 environment and so I update the system:

Code: Select all

sudo yum update -y

But I received one error message:

Code: Select all

I googled but didn't find solutions to it.

Those are not CentOS suppllied kernels: kernel-3.10.0-957.21.3.el7.toa.x86_64

The kmod-kvdo package depends on you having the correct CentOS supplied kernel installed. You appear to be using someone else's and they either obscure the CentOS supplied ones or they have been excluded or the repo is not enabled.

Further info:

Code: Select all

$ rpm -qf /etc/redhat-release
centos-release-7-6.1810.2.el7.centos.x86_64
(base) [congmin@localhost]$ uname -s -r
Linux 3.10.0-957.21.3.el7.toa.x86_64

So you mean this is not the official kernel from CentOS? How to solve this issue? Must I have to reinstall the whole system?

[TrevorH]

Linux 3.10.0-957.21.3.el7.toa.x86_64

No, that kernel has ".toa." in its name and no CentOS kernel has that. Google's not being very helpful with that but I suspect it might be some sort of alibaba cloud special?

So you mean a user can install CentOS 7.0, but use a kernel different from the standard one from RedHat? I don't manage the machine.

Post the output from rpm -qa kernel\* \*release | sort

[martinmin]

Here they are:

$ rpm -qa kernel\* \*release | sort

kernel-3.10.0-957.21.3.el7.toa.x86_64
kernel-3.10.0-957.el7.x86_64

So you have both the original 7.6 distro kernel installed (the bottom one) and this foreign one. If you run yum list installed kernel it should show you a line for each one and the right hand side says which repo it was installed from e.g. @updates.

[martinmin]

So, how to resolve this system update failure? Should I ask to remove the foreign kernel? What's the purpose of having multiple kernels in one OS system?
