Description of problem: After updating to latest rsyslog-8.30.0-3 it fails to start. Version-Release number of selected component (if applicable): 8.30.0-3 How reproducible: Always at system startup Steps to Reproduce: 1. Run # systemctl start rsyslog.service Actual results: Job for rsyslog.service failed because the control process exited with error code. Expected results: The daemon should start Additional info: Manually starting it as "rsyslogd -n -d" results in rsyslogd: symbol lookup error: rsyslogd: undefined symbol: fjson_global_do_case_sensitive_comparison Googling the case I found: https://github.com/rsyslog/rsyslog/issues/1853 I have installed libfastjson-0.99.6-1.fc26.x86_64
Looks like a dependeny was not released fast enough: Try: # yum update --enablerepo updates-testing libfastjson this installs: libfastjson-0.99.7-1.fc26 and now rsyslogd will start again
