Hello,  
I have been using the standard version of MySQL 8.0 but wanted to switch. As far as I understand it should be supported for Ubuntu but it fails every time on the (–fix-broken install commands not helping either) installation process. Before the installation I made sure to remove every existing mysql package. It goes fine up until the 7. step in [the guide](https://docs.percona.com/percona-server/8.0/installation/apt-repo.html) but I get the following error when running the 8. step.

```

I have followed the advice of someone on the askUbuntu forum to check the logs but I couldn’t find anything noteworthy. Is there any solution I could try?

I tried the 8.0.31 and .30 versions on Ubuntu 22.04 with APT.

Hi @kaPa  
I’ve checked the installation process on Ubuntu Jammy(22.04) and all goes fine as per the documentation.  
Have you removed the old “/var/lib/mysql/” directory from the previous mysql installation? If not, please **make a backup** of that folder(in order not to lose data if you have any there), remove/or move into safe folder the “/var/lib/mysql/” directory and try to rerun the installation process.
