Kernel-debuginfo packages for latest kernel missing from debug repos

Latest response

Hi all,

I hope I'm doing something wrong here, we are trying to debug (systemtap) kernel tcp resets in one of our rhel6 servers but it seems the latest rhel6 debug repos do not have a kernel-debuginfo package for the latest rhel6 kernel, see below:

[root@host1 ~]# stap-prep
Need to install the following packages:
kernel-debuginfo-2.6.32-754.41.2.el6.x86_64

I tried searching redhat's ftp site but I still don't see it there either.

I've found https://access.redhat.com/solutions/9907 which refers to this issue but for RHEL5 and the solution did not make a difference.

I've checked our connected satellite server and all our repos have synced correctly today (daily sync plan)

Does anyone know where I can find kernel-debuginfo.2.6.32-754.41.2.el6.x86_64?

Thanks in advance!

Hi Antonio,

Seems the package kernel-debuginfo.2.6.32-754.41.2.el6.x86_64 doesn't exit at all ... the latest one is 2.6.32-754.35.1 indeed.
Please note that RHEL 6 is EOL (end-of-life) ... you should consider migrating to a supported edition - RHEL 7 or RHEL 8 ! :)

Regards,
Christian

Hi Christian,

I see, thanks for checking.

Antonio P.

You're welcome, Antonio ! :)

Anyone landing here, please know RHEL 6 has reached it's end of Maintenance II, meaning if you want support, you must pay for Extended Update Support. Please see this important discussion on the status of RHEL 6.

Please update to a fresh new supported Operating System that has regular updates.

Kind Regards,
RJ

Hello Antonio,

I don't know why you can't find kernel-debuginfo.2.6.32-754.41.2.el6.x86_64. It was part of RHSA-2021:2735. If you are still having trouble accessing that kernel-debuginfo, please open a support case.

Regards. Marc

Hi Marc,

I'm not seem to be the only one, Christian above couldn't find it either. I'll open a support case and revert back with findings.

Thanks Antonio P.

Hi Marc,

Does one possibly need to have an EUS subscription to access the package ? :)

Regards,
Christian

Hi Christian,

Yes, an EUS subscription is necessary to access the package.

Regards, Marc

Hi Marc,

That's what I assumed ... Thank you ! I don't have an EUS subscription, because I don't need it.
So Antonio, either you purchase this subscription or you use supported "non-EOL" editions. :)

Regards,
Christian
