Problem with Repo for 5.7?

Hello,
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


The following additional packages will be installed:
libaio1 libdbd-mysql-perl libdbi-perl libmysqlclient20
libperconaserverclient18.1 mysql-common percona-server-client-5.6
percona-server-common-5.6 percona-server-server-5.6
Suggested packages:
libclone-perl libmldbm-perl libnet-daemon-perl libsql-statement-perl tinyca
The following NEW packages will be installed:
libaio1 libdbd-mysql-perl libdbi-perl libmysqlclient20
libperconaserverclient18.1 mysql-common percona-server-client
percona-server-client-5.6 percona-server-common-5.6 percona-server-server
percona-server-server-5.6

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]

maybe the Repos got mixed?

Kind Regards
