Summary

Removed references to Ubuntu Server 20.10 STR from installation documentation and version compatibility lists

Security assessment

The changes involve removing mentions of Ubuntu 20.10 STR from compatibility lists and instructions. This appears to be routine documentation maintenance to reflect current supported versions rather than addressing security vulnerabilities. No security-related context or vulnerability mentions are present in the diff.
