Checkmk on RHEL 9.7 and/or RHEL 10.1 issues

Troubleshooting
1

Just want to make you aware that Red Hat rebased OpenSSL in RHEL 9.7 and 10.1 to version 3.5.

This leads to many commands (e.g. nslookup, rpmbuild, etc) no longer working when run as site user because if its LD_LIBRARY_PATH settings and Checkmk comes with some own libraries (like ~/lib/libcrypto.so.3).

running such commands then lead to errors like this:

OMD[dev24b]:~$ nslookup bla
nslookup: /omd/sites/dev24b/lib/libcrypto.so.3: version `OPENSSL_3.4.0’ not found (required by /lib64/libisc-9.16.23-RH.so)

or errors during agent baking as shown in:

We’re running into this same issue after updating to RHEL 9.7. I’ve got a support case open, hoping they push a fix out soon.

Same issue on our CEE instance (2.4.0p16) on Alma 9.7. Were you able to find a workaround?

Support responded and said it’s being sent over to development. Sounds like we’re stuck until they release a fix.
