Creating site on OEL8 throws a traceback

cporter · December 2, 2022, 8:56pm

I’ve installed check-mk-enterprise-2.1.0p17.x86_64 on Oracle Enterprise Linux 8. When I try to create a new site I get the traceback show below. I am currently using checkmk for other sites using OEL7. Is there any hope to fix this or will I have to downgrade?

Thanks for any input.

Sorry for the poorly formatted output. I used the preformat tag but it spread the output all over the place.

chauhan_sudhir · December 6, 2022, 9:36pm

What does the output of the following comma f looks like :

rpm -qa|grep -i mk

cporter · December 7, 2022, 7:32pm

$ rpm -qa | grep mk
oddjob-mkhomedir-0.34.7-2.el8.x86_64
check-mk-enterprise-2.1.0p17-el7-38.x86_64

Also

$ rpm -qa | grep ^openssl
openssl-1.1.1k-7.el8_6.x86_64
openssl-libs-1.1.1k-7.el8_6.x86_64

Looks like an openssl version mismatch but I’m not sure how to get around it. I’ve seen where other folks have installed checkmk successfully on OEL8 so I’m not sure what I’m doing wrong.

aeckstein · December 7, 2022, 7:39pm

Isn´t the -el7- in the rpm name of the checkmk package an indicator for the package to be installed on EL 7 and should be -el8- ?
As in check-mk-enterprise-2.1.0p17-el8-38.x86_64.rpm ?

cporter · December 7, 2022, 7:45pm

I’m pretty sure it’s for OEL8

openssl-libs-1.1.1k-7 <dot> el8_6.x86_64

I’m happy to be incorrect if it gets me closer to making this work.

chauhan_sudhir · December 7, 2022, 7:49pm

You have installed a wrong package on OEL8. The package should be el8. It’s a classic. Happens to me often when I switch from CentOS 7 to Rocky/Alma8.

Have a look at the name of the file:
wget --user={USERNAME} https://download.checkmk.com/checkmk/2.1.0p17/check-mk-enterprise-2.1.0p17-el8-38.x86_64.rpm --ask-password

cporter · December 7, 2022, 8:31pm

Thank you for pointing this out to me. I’m quite embarrassed that I didn’t catch that. Our main checkmk installation is OEL 7 so I just copied the package to the OEL8 instance without thinking.

Installation was successful and I was able to create a site.

Apologies for cluttering up this space with this nonsense.

Thanks very much for all the help…

chauhan_sudhir · December 7, 2022, 8:52pm

All good. No problem.
