I’m trying to install PXC 5.7 on Rocky Linux 8 and I require jemalloc. However, when I try to install it via `yum -y install jemalloc-devel`, I get the following error:

```auto

Error:
 Problem: cannot install the best candidate for the job
  - nothing provides jemalloc = 3.6.0-1.el8 needed by jemalloc-devel-1:3.6.0-1.el8.x86_64 from pxc-57-release-x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

```

```auto
yum list *jemalloc*

Installed Packages
jemalloc.x86_64 1:3.6.0-1.el8 @pxc-57-release-x86_64
Available Packages
jemalloc-debuginfo.x86_64 1:3.6.0-1.el8 pxc-57-release-x86_64
jemalloc-debugsource.x86_64 1:3.6.0-1.el8 pxc-57-release-x86_64
jemalloc-devel.x86_64 1:3.6.0-1.el8 pxc-57-release-x86_64

```

For some reason, the `jemalloc-devel-1:3.6.0-1.el8.x86_64` in the official repo requires `jemalloc = 3.6.0-1.el8`, but only `jemalloc = 1:3.6.0-1.el8` is available.

For now I fixed this by running `yum -y install jemalloc-devel --nobest`, but this requires a repo fix.
