Hello @poltpolt ,
Maybe try using new Percona Toolkit version - 3.7.0-2 .

This is this version , it just present itself in a strange way that omits the number
sudo apt show percona-toolkit
Package: percona-toolkit
Version: 3.7.0-2.noble
Status: install ok installed
Do you have any idea how to get permisions to raise a bug report on percona jira? I can browse the bugs but no way to raise new one.
the PT doc says
Please report bugs at [https://jira.percona.com/projects/PT](https://jira.percona.com/projects/PT).
But it does not work, the contact page on percona site also does not work

You dont need any extra permissions to raise bug in Percona Jira. It might be your account limiting to. Can you try with your personal email?

This works as well.
pt-deadlock-logger also run fine pointing to the instance.
```auto
PT_DEBUG=1 pt-deadlock-logger h=127.0.0.1 --port 13066 --user=root --ask-pass
Enter MySQL password:
```
My Server version,
```auto
Server version: 11.8.5-MariaDB-ubu2404 mariadb.org binary distribution
```
Can you send your full pt-deadlock command and along with PTDEBUG enabled?
