checkmk - problem with agent bakery on rocky linux 9 and version 2.4.xx

 building a new checkmk agent version does work anymore you get errors like:

Exception (Crash ID: e8bcbbf8-cf9d-11f0-b0e1-005056954460): Error running automation call bake-agents (exit code 2), error: 

[Errno 2] No such file or directory: '/omd/sites/mysite/var/check_mk/agents/linux_rpm/packages/06fbdffff052e88dfa48'



another error was:

Exception (Crash ID: b3d7e7f6-cfa1-11f0-9e5c-005056954460): Error running automation call bake-agents (exit code 1), error: 

Error baking agent 573f3d061ca33337/linux_rpm: Error building RPM packet.



>>> after doing some analysis I found, you can see an error by just running "rpmbuild" as console user in the site:

OMD[mysite]:

if you are in the checkmk site on console and run "rpmbuild" you get a:

rpmbuild

rpmbuild: /omd/sites/mysite/lib/libcrypto.so.3: version `OPENSSL_3.4.0' not found (required by /lib64/librpmio.so.9)





>>> solution: wait for checkmk version 2.4.0p17 

https://checkmk.com/werk/18935



To fix this, we now wrap the affected commands to ensure they use the system-supplied OpenSSL library when run by an OMD site user. The wrapped commands are:

    curl

    nslookup

    pdftoppm

    rpmbuild

    scp

    ssh

    zypper





Users running Baking agents on the following operating systems may have experienced failures due to this issue:



    SLES 15 SP5, 15 SP6, 15 SP7

    RHEL 9, 10

    Debian 13
