I used to run ubuntu 16 with pxc 5.7. After updating to Ubuntu 20.04.2 LTS, I ran the following commands to update the cluster to 8.0:
apt-get remove percona-xtradb-cluster-server-5.7
apt autoremove
wget https://repo.percona.com/apt/percona-release_latest.generic_all.deb
dpkg -i percona-release_latest.generic_all.deb
apt-get update
percona-release setup pxc80
apt update
percona-release enable tools release
apt update
apt install percona-xtradb-cluster
During the installation process, the following error is encountered:
Do you want to continue? [Y/n]

The folder /var/lib/mysql doesn’t exist on my machine. I would assume that percona installs it, because it also installed a mysql binary at /usr/bin during the failed installation mentioned above.
What am I missing here?
