Repo for installing MySQL 8.0

I have a question about repos for installing mysql 8.0 on Ubuntu.
Due to this article…/apt_repo.html I need to use

wget [URL][/URL].$(lsb_release -sc)_all.deb

But for using pmm2 ( we need to use:


So my first question is what repo I should use in case if I am using ubuntu bionic, mysql 8.0, pt-tool, Xtrabackup, pmm1 and pmm2.

Is there any difference between percona-release_latest.bionic_all.deb and percona-release_latest.generic_all.deb in ? Those debs have the same size and the same date creation.

Percona-Server-8.0 is in repo
percona-toolkit, percona-xtrabackup and pmm packages are in repo
If you want to install all of them you should just execute and these repos will be enabled

No, they are all the same


Thanks Lorraine.
