Upgrade to v56 fails with cpanel-perl conflict

I can't resist. From the moment I saw the announcement to 522, I saw this coming, though I was hoping it wouldn't happen.

I just tried to update a server:

Code:

So what's the recommended path to get this running now?

 

No, this has been a fresh installation a few weeks ago with no system changes.

Code:

# cat /var/cpanel/rpm.versions.d/local.versions

--- 

file_format: 

  version: 2

install_targets: {}


rpm_locations: {}


srpm_sub_packages: {}


srpm_versions: {}


target_settings: 

  analog: uninstalled

  awstats: uninstalled

  clamav: installed

  easy-tomcat7: uninstalled

  munin: installed

  webalizer: uninstalled

url_templates: {}

 

Ok, I opened a support request with the ID 7528903.
