Hi All,

I am trying to upgrade from Rocky8 to Rocky9 using leapp  
sudo leapp preupgrade  
Traceback (most recent call last):  
File “/usr/local/bin/leapp”, line 11, in   
load\_entry\_point(‘leapp==0.14.0’, ‘console\_scripts’, ‘leapp’)()  
File “/usr/local/lib/python3.6/site-packages/leapp-0.14.0-py3.6.egg/leapp/cli/ **init**.py”, line 37, in main  
cli.command.execute(‘leapp version {}’.format(VERSION))  
File “/usr/local/lib/python3.6/site-packages/leapp-0.14.0-py3.6.egg/leapp/utils/clicmd.py”, line 105, in execute  
self.\_sub\_commands[cmdname].parser.error(leftover)  
KeyError: ‘leapp’

here is a kb article about this but I do not have access

> **[leapp preupgrade failed with a python traceback KeyError: 'leapp' - Red Hat...](https://access.redhat.com/solutions/6896571)**

Rocky does not support in-place conversion to different distro. (8 and 9 are two distros.)

You have to ask from where-ever youdid get the leapp from.

Here is the output from the RHEL KB article:

## Resolution

- Execute the following command to check whether you have the `leapp-upgrade-el7toel8` & `leapp-upgrade-el7toel8-deps` packages installed on the RHEL 7.9 system.
- Execute the following command to check whether you have the `leapp-upgrade-el8toel9` & `leapp-upgrade-el8toel9-deps` packages installed on the RHEL 8.8 system.
- If not, execute the following command to install the `leapp-upgrade-elXtoelX` & `leapp-upgrade-elXtoelX-deps` packages. Depending on your RHEL version, replace ‘X’ with your package version.

[Raw](https://access.redhat.com/solutions/6896571#)

```auto
# yum install leapp-upgrade-elXtoelX leapp-upgrade-elXtoelX-deps

```

- For offline systems, Download packages and their dependencies from the Red Hat customer portal : [Red Hat Customer Portal](https://access.redhat.com/downloads/content/package-browser)

## Root Cause

- **The packages required for leapp installation are provided by extra repos ( rhel-7-server-extras-rpms ) on the RHEL 7.9 system.**
- **The packages required for leapp installation are provided by appstream repos ( rhel-8-for-x86\_64-appstream-rpms) on the RHEL 8.8 system.**
- The error happens when packages are manually installed on a system and some packages are missing.
