I see it in the repository, by following the guide at https://docs.percona.com/percona-server/8.0/installation/apt_repo.html:
I’ll test it these days
Hi George,
Any update on percona-xtradb-cluster 80 on Ubuntu 22.04.1?
We can see packages in ps80 repo but not in pcx80. Can you please give us a timeline?
Many thanks!
Just tried today and found this thread, cluster seems to be missing as of now. Would be interested in a timeline too, as I want some 22.04 nodes to join our cluster 
same here, ubuntu server 22.04 trying to install percona xtradb cluster 8
Waiting you news
We also got a good amout of clusters we need to upgrade to 22.04.
The lack of news worries me.
Are you dropping support for 22.04? If so please let us know so we can look for alternatives for our customers.
Was really surprised support for jammy hasn’t been added yet for xtradb.
We have support for PS-80, PXC-80 PXB-80 for ubuntu jammy.
So you just need to enable product repos using percona-release script
If Ubuntu 22.04 is supported, can you please update the matrix here: https://www.percona.com/services/policies/percona-software-support-lifecycle
