Good afternoon my friends, I’m Brazilian so sorry for my not very good English. Today I installed percona on my ubuntu 20 to migrate mysql 5.7.42 to sql google cloud however when installing percona I had the misfortune of no longer having access to mysql, from what I understand in the logs ubuntu is trying to use mysql 8.0 which It was installed with percona, I need to return it to normal as it was before, below I include some system logs: sudo apt-cache policy mysql-server mysql-server: Installed: 5.7.42-1ubuntu18.04 Candidate: 5.7.42-1ubuntu18.04 Version table: 8.0.40-0ubuntu0.20.04.1 500 500 [Index of /ubuntu](http://us-central1.gce.archive.ubuntu.com/ubuntu) focal-updates/main amd64 Packages 500 [Index of /ubuntu](http://security.ubuntu.com/ubuntu) focal-security/main amd64 Packages 8.0.19-0ubuntu5 500 500 [Index of /ubuntu](http://us-central1.gce.archive.ubuntu.com/ubuntu) focal/main amd64 Packages \*\*\* 5.7.42-1ubuntu18.04 1001 500 [Index of /232905/apt/ubuntu](http://repo.mysql.com/apt/ubuntu) bionic/mysql-5.7 amd64 Packages 100 /var/lib/dpkg/status N: Ignoring file ‘mysql-apt-config\_0.8.10-1\_all.deb’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extension ---
