Hello @antones - at a glance, off the bat I can note that the v2021.10 EaaSI release components do not/did not support Ubuntu 22.04, it was maintained for 18.04, 20.04 and CentOS/RHEL 7. It is highly likely that there are multiple dependency/version issues in the chain. At a minimum you are likely experiencing the same jboss/keycloak deprecation issues described in ERROR when installing from scratch (jboss/keycloak, repository does not exist) - #2 by ethan.gates
Please be aware, as I noted in that thread as well, that we are currently largely stepping back from active feature development and maintenance of the now-aging v2021.10 codebase in order to examine dependency and tooling issues throughout the dev workflow, so our ability to continue supporting deployments, especially self-deployments, of these older versions and components from ~2021 will be extremely limited. We’re in a transitional moment and working hard to ultimately make the platform and its development both more maintainable - there will be more details posted soon in the Program Announcements and both the Handbook and the Forum here will be updated shortly in order to more accurately reflect our current status, and we’ll make instructions for testing a more up-to-date version of the software available when able, I apologize for any confusion
