Docs feedback: Page needs serious upgrade
I read https://docs.gitlab.com/ee/administration/integration/plantuml.html and tried to follow the Debian/Ubuntu instructions, but they are seriously out-of-date:
It says to install git-core, that package has been renamed to git in any reasonably new Debian/Ubuntu
It says to install openjdk-7-jdk, that package is not available on Debian Stretch (I don’t think I have any machines running Jessie around to check how it was in that) and on Ubuntu Xenial (don’t know how far back) and newer.
It says to install tomcat7, that package is actually available on Ubuntu Xenial, but not on Ubuntu Bionic or Debian Stretch.
There's also an issue which seems to be due to changes in GitLab:
It says that the service will be ready and listening on port 8080. Even if I didn’t make other mistakes in my test, the fact the GitLab is listening on that port will prevent tomcat from doing so. It might have been fine with GitLab 8.16 when the feature was added (according to the page), but now it seems wrong.
