i like the new approach with the Percona Repo being able to install 8.0, 5.7 and 5.6 with the same Repo. However i think we found a Problem.
percona-release setup ps57 apt update apt-get install percona-server-server percona-server-client
lead to 5.6 beeing installed

Need to get 15.2 MB of archives. After this operation, 146 MB of additional disk space will be used. Do you want to continue? [Y/n]
