Resolution

Remove all packages from the exclude list in /etc/dnf/dnf.conf by one of the methods below:

• Manually remove packages from the exclude list by editing /etc/dnf/dnf.conf

  $ vim /etc/dnf/dnf.conf
   [main]
   gpgcheck=1
   installonly_limit=3
   clean_requirements_on_remove=True
   best=True
   skip_if_unavailable=False
   exclude=           -----===> Remove all packages
  

• Or remove all packages from the exclude list by one command as below:

  $ dnf config-manager --save --setopt exclude=''
  

• Please refer to Performing post-upgrade tasks from (RHEL 7 to RHEL 8) and Performing post-upgrade tasks from (RHEL 8 to RHEL 9) for more details

Root Cause

• During in-place upgrade, packages includingleapp and snactor are automatically added to exclude list to prevent critical files from being removed or updated
• After in-place upgrade, those packages must be removed from exclude list before they can be removed from the system

Diagnostic Steps

• Packages includingleapp and snactor are added to exclude list in /etc/dnf/dnf.conf

  [main]
  gpgcheck=1
  installonly_limit=3
  clean_requirements_on_remove=True
  best=True
  skip_if_unavailable=False
  exclude=python2-leapp,snactor,leapp-upgrade-el7toel8,leapp
