Hi @Milan,

Glad switching to pdps-8.0 fixed it. As @Vadim_Yalovets mentioned, the tools repository is deprecated. Migrating to product-specific repos like pdps-8.0 is the recommended path forward.

For context, here’s the root cause. The tools repo `libdbd-mysql-perl 1:5.013-1.noble` ships a `mysql.so` that isn’t linked against `libmysqlclient` at all. As the library is never loaded, every `mysql_*` symbol is missing at runtime:

```auto
# Tools repo (broken, no libmysqlclient linkage)
$ nm -D mysql.so | grep sqlstate
                 U mysql_sqlstate

# Ubuntu (working, properly linked)
$ nm -D mysql.so | grep sqlstate
                 U mysql_sqlstate@libmysqlclient_21.0

```

The tools repo package uses **epoch `1:`** , so `apt upgrade` silently replaces the working distro version with the broken one. The same issue affects Debian. See [#40009](https://forums.percona.com/t/percona-toolkit-pt-show-grants-3-7-1-broken-on-debian-13/40009) for details.

**Recommended fix:** migrate to the product-specific repository as Vadim described. The `pdps-8.0` repo ships a properly built package.

As a last resort, you can pin the distro version temporarily. This is not recommended long term since the tools repo will not receive further updates:

```auto
apt-get install --allow-downgrades libdbd-mysql-perl=4.052-1ubuntu3
apt-mark hold libdbd-mysql-perl

```
