In the CRE deb package for Ubuntu 22.04 (and probably others), there is a bug with active checks that depend on openssl, e.g. check_http
, check_ftp
, check_tcp
etc. These checks go critical after the update, saying
(Return code of 127 is out of bounds - plugin may be missing)
Workaround:
Symlink the old libraries like so (you might need to adapt the paths to your environment):
cd /opt/omd/versions/2.2.0p15.cre/lib
ln -s /opt/omd/versions/2.2.0p14.cre/lib/libcrypto.so.1.1
ln -s /opt/omd/versions/2.2.0p14.cre/lib/libssl.so.1.1
I have already notified feedback@checkmk.com about this.
