Recently updated my syslog-ng server and libjson-c4 was upgraded to libjson-c5 and c4 was removed from the repository. Through troubleshooting I was trying to reinstall syslog-ng and ran into missing depends error below:

The following packages have unmet dependencies: syslog-ng-core : Depends: libjson-c4 (>= 0.13.1) but it is not installable Depends: libssl1.1 (>= 1.1.1) but it is not installable

From research it looks like libjson-c4 has been replaced in the Debian repositories by libjson-c5 is there a way to utilize the libjson-c5 version or how should I resolve this issue? FYI this was working on Ubuntu 22.04 Jammy up until the past week. I ran updates on the system to resolve another issue and after that I’m getting an error starting the daemon
