  I am a student and am studying your software. And I wanted to understand - what is the practical meaning of this? bing9 app packages are not updated. And the new packages eliminate security vulnerabilities.

Please clarify - install the current Ubuntu 23.04.3 and then the CyberPanel 2.3.4 package yielded poor results because… tests failed?
Maintenance documentation is based on Ubuntu 18.04

My opinion is this. It is not correct to post the current disk image of the LiteSpeed ​​software along with historical documentation (namely, Ubuntu 18.04). There is some kind of negligence in this.
