• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Resolved Plesk won't install on Alma 9 because of missing CRB repo

Server operating system version
Almalinux 9.3
Plesk version and microupdate number
18.0.60
After my efforts to spin up a Rocky 9 server were swatted by Plesk not actually supporting Rocky 9, I've now spun up an Alma 9 server and worked my way back to being ready to install Plesk.

This time I got the following error:

Plesk installation requires 'crb' OS repository to be enabled.

So I enabled and tried again:

# dnf config-manager --set-enabled crb

And got the following:

Unable to create dnf cache for 'crb' OS repository.
Make sure the repository is available, otherwise either disable it or fix its configuration, then try again.

I then tried an update to pull the cache, and:

# dnf update
Error: Cannot find a valid baseurl for repo: crb

At this point I checked my dnf repolist and see that Rackspace, our server host, seems to replace the CRB repo

# dnf repolist
repo id repo name
crb AlmaLinux 9 - CRB
devel AlmaLinux 9 - Devel
epel Extra Packages for Enterprise Linux 9 - x86_64
epel-cisco-openh264 Extra Packages for Enterprise Linux 9 openh264 (From Cisco) - x86_64
ospc Open Source Public Cloud
rackspace Rackspace Monitoring
rackspace-almalinux-appstream AlmaLinux 9 - AppStream
rackspace-almalinux-baseos AlmaLinux 9 - BaseOS
rackspace-almalinux-crb AlmaLinux 9 - CRB
rackspace-almalinux-extras AlmaLinux 9 - Extras

Note there's both a crb and rackspace-almalinux-crb repo ID listed here, both with the same AlmaLinux 9 - CRB repo name. If I again disable crb, the Rackspace variant persists.

It seems to me that basically, with Rackspace we already have a CRB repo enabled by default and working, but the Plesk installer is looking for one named exactly "crb" so erroring out.

Is there a way to force the installer to continue despite thinking this repo is missing?
