If you choose to call a function ONLY reply in the following format with NO suffix:

<IMPORTANT>
Reminder:
- Function calls MUST follow the specified format: an inner <function=...></function> block must be nested within <tool_call></tool_call> XML tags
- Required parameters MUST be specified
- You may provide optional reasoning for your function call in natural language BEFORE the function call, but NOT after
- If there is no function call available, answer the question like normal with your current knowledge and do not tell the user about function calls

You are tasked with managing Personal Package Archives (PPAs) on an Ubuntu server system. The system has accumulated multiple PPAs over time, and you need to create a solution that:

1. Identifies all currently installed PPAs on the system
2. Removes specified PPAs using appropriate methods
3. Handles package downgrades when PPAs are removed (packages should revert to official repository versions where possible)
4. Cleans up residual configuration files from removed PPAs
5. Generates a summary report of what was removed and which packages were affected

The system has PPAs stored in `/etc/apt/sources.list.d/` as `.list` files. Some packages from these PPAs may be installed, and removing the PPA should handle these packages gracefully. You should implement a solution that can remove PPAs by name (e.g., "ppa:whatever/ppa") and optionally handle package downgrades or removal.

Your solution should be command-line based and handle edge cases such as:
- PPAs that have already been partially removed
- Packages that exist in both PPA and official repositories
- Multiple PPAs providing the same packages
- Invalid or broken PPA configurations

When finished, call `submit_solution` to run the test suite and get your score.

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to

## Ubuntu distribution repository
##
## The following settings can be adjusted to configure which packages to use from Ubuntu.
## Mirror your choices (except for URIs and Suites) in the security section below to
## ensure timely security updates.
##
## Types: Append deb-src to enable the fetching of source package.
## URIs: A URL to the repository (you may add multiple URLs)
## Suites: The following additional suites can be configured
##   <name>-updates   - Major bug fix updates produced after the final release of the
##                      distribution.
##   <name>-backports - software from this repository may not have been tested as
##                      extensively as that contained in the main release, although it includes
##                      newer versions of some applications which may provide useful features.
##                      Also, please note that software in backports WILL NOT receive any review
##                      or updates from the Ubuntu security team.
## Components: Aside from main, the following components can be added to the list
##   restricted  - Software that may not be under a free license, or protected by patents.
##   universe    - Community maintained packages. Software in this repository receives maintenance
##                 from volunteers in the Ubuntu community, or a 10 year security maintenance
##                 commitment from Canonical when an Ubuntu Pro subscription is attached.
##   multiverse  - Community maintained of restricted. Software from this repository is
##                 ENTIRELY UNSUPPORTED by the Ubuntu team, and may not be under a free
##                 licence. Please satisfy yourself as to your rights to use the software.

You are tasked with managing Personal Package Archives (PPAs) on an Ubuntu server system. The system has accumulated multiple PPAs over time, and you need to create a solution that:

1. Identifies all currently installed PPAs on the system
2. Removes specified PPAs using appropriate methods
3. Handles package downgrades when PPAs are removed (packages should revert to official repository versions where possible)
4. Cleans up residual configuration files from removed PPAs
5. Generates a summary report of what was removed and which packages were affected

The system has PPAs stored in `/etc/apt/sources.list.d/` as `.list` files. Some packages from these PPAs may be installed, and removing the PPA should handle these packages gracefully. You should implement a solution that can remove PPAs by name (e.g., "ppa:whatever/ppa") and optionally handle package downgrades or removal.

Your solution should be command-line based and handle edge cases such as:
- PPAs that have already been partially removed
- Packages that exist in both PPA and official repositories
- Multiple PPAs providing the same packages
- Invalid or broken PPA configurations

When finished, call `submit_solution` to run the test suite and get your score.
