Problem: We are unable to upgrade percona xtradb cluster from 8.0.30-22-1 to 8.0.31-22-1 on master node where percona xtra backup is installed

What we have done to install percona xtra db cluster and percona xtra backup:

1. sudo apt update
2. sudo apt install -y wget gnupg2 lsb-release curl
3. wget [https://repo.percona.com/apt/percona-release\_latest.generic\_all.deb](https://repo.percona.com/apt/percona-release_latest.generic_all.deb)
4. sudo dpkg -i percona-release\_latest.generic\_all.deb
5. sudo apt update
6. sudo percona-release setup pxc80
7. sudo apt install -y percona-xtradb-cluster
8. wget [https://repo.percona.com/apt/percona-release\_latest.$](https://repo.percona.com/apt/percona-release_latest.$)(lsb\_release -sc)\_all.deb
9. sudo dpkg -i percona-release\_latest.$(lsb\_release -sc)\_all.deb

Why did you run steps #8 and #9? Those are just duplicate steps of #3 and #4.

In order to upgrade PXC 8.0.30 to 8.0.31, you simply need to install/upgrade the PXC package on each PXC node, one at a time.

Shutdown node3. Upgrade node3. Start PXC node3. It will upgrade and then IST any delta. Repeat for node2. Repeat for node1. Do _not_ write to any node which is 8.0.31 until ALL nodes are 8.0.31.
