Re: BUG #18561: postgresql16-devel rpm cannot be installed due to missing Perl-IPC-Run

I also tried to install it like it says.

```

[redhat(at)bf9eab65c5de src]$ sudo -i dnf install config-manager
Rocky Linux 9 - BaseOS 11 kB/s | 4.1 kB 00:00
Rocky Linux 9 - AppStream 14 kB/s | 4.5 kB 00:00
Rocky Linux 9 - Extras 6.8 kB/s | 2.9 kB 00:00
No match for argument: config-manager
Error: Unable to find a match: config-manager[redhat(at)bf9eab65c5de src]$
```

I think I have to just edit yum repos by hand.

To enable the crb repository:

- Open /etc/yum.repos.d/rocky.repo.
- Locate the [crb] section.
- Change enabled=0 to enabled=1.
- Save the file.
- Run sudo dnf update.
