Unable to update from Znuny LTS 6.4.2 to LTS6.5.4

To everyone using the znuny community

I have a question.

I am having trouble updating Znuny (LTS6.4.2 → LTS6.5.4) in the RHEL8 environment.

The following error always occurs in the check module.
There was similar content in past communities, but in my environment, even if I used it as a reference, it did not improve.

I will write down the error points from my execution results.

However, it just doesn't work.
Has anyone been able to solve it in another way?
