I can't install java in libresign

Describe the bug

occ libresign:install --java does not work

To reproduce

Good afternoon, I am having a strange problem while installing LibreSign. When I try to install java using "occ libresign:install --java", I receive a notification that the installation was successful, but when I check with "occ libresign:configure:check", I see that java is not installed. When I try to sign a document, I get an error saying "Java path not set". I have java installed on my operating system, and it is working properly. I have been struggling with this issue for some time now. Where should I go to resolve this problem?

Reproduce the issue with occ libresign:install --java and then occ libresign:configure:check on the reported Ubuntu and LibreSign versions. Review the LibreSign command and Java configuration paths; done means the check detects Java after installation and document signing no longer reports that the Java path is unset.
