Hi @CostelLI tried to reproduce your issue but without success. What commands I have executed to reproduce: ```auto wget https://repo.percona.com/prel/apt/pool/main/p/percona-release/percona-release_1.0-25.generic_all.deb sudo dpkg -i percona-release_1.0-25.generic_all.deb sudo apt update sudo apt-get install percona-xtradb-cluster-5.7 ``` What I get in result: ```auto vagrant@ubuntu-xenial:~$ dpkg -l | grep percona ii percona-release 1.0-25.generic all Package to install Percona gpg key and AP T repos ii percona-xtrabackup-24 2.4.21-1.xenial amd64 Open source backup tool for InnoDB and Xt raDB ii percona-xtradb-cluster-5.7-dbg 5.7.31-31.45-3.xenial amd64 Debugging package for Percona XtraDB Clus ter ii percona-xtradb-cluster-client-5.7 5.7.31-31.45-3.xenial amd64 Percona XtraDB Cluster database client bi naries ii percona-xtradb-cluster-common-5.7 5.7.31-31.45-3.xenial amd64 Percona XtraDB Cluster database common fi les (e.g. /etc/mysql/my.cnf) ii percona-xtradb-cluster-server-5.7 5.7.31-31.45-3.xenial amd64 Percona XtraDB Cluster database server bi naries ``` ---

Hello, Maybe it’s the repo that I use. I have this: ```auto cat /etc/apt/sources.list.d/percona.list # PERCONA repo deb http://repo.percona.com/apt xenial main deb-src http://repo.percona.com/apt xenial main ``` The helper package seems to create (notice the extra percona in the path): ```auto deb http://repo.percona.com/percona/apt xenial main ``` From the above it worked well. I was trying to install: ```auto percona-xtradb-cluster-full-57 ``` Now I switched to install: ```auto percona-xtradb-cluster-server-5.7 ``` and this is ok because the “-dbg” is not a dependency. We are doing the install automatically (via salt-stack) and it has been like it is now for a long time. I know for sure that it worked a couple of weeks ago because we did the exact same thing and there was no failure. I guess I just need to update to the new repo path and/or rebuild the install to use the helper package, but maybe there are others that use the old paths. Thank you. ---

Usually such issue might appear in the following case: packages in repo were updated but apt-cache on the system was not updated. So try to perform apt-get update before the installation of dbg package ---

I had run it before (and anyway salt should have run it after adding the repo), however now I cannot reproduce it anymore. I see that we get different IP addresses when doing dig, so maybe I was just getting to a bad mirror as you suggested. Anyway I consider my question asked. Really really appreciate the quick responses. ---
