Ubuntu Upgrade from 20.10 to 21.04 or 21.10 not possible

Question

I currently have the problem that I cannot update from Ubuntu 20.10 to 21.04 or 21.10.

My Ubuntu Version:

Distributor ID:Ubuntu
Description:Ubuntu 20.10
Release:20.10
Codename:groovy

I would like upgrade to next higher verson, but still not work, following steps were done:

1. Set Archive Package

   sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
   

2. Upgrade Packages:

   sudo apt-get update && sudo apt-get dist-upgrade
   

3. Reboot OS

4. sudo do-release-upgrade

   Output:

   Reading cache
   Checking package manager
   Can not upgrade
   An upgrade from 'groovy' to 'impish' is not supported with this tool.
