How To Explicitly Accept PPA Label Change in Ubuntu?

Ubuntu 8

In this article, we will explore how to explicitly accept a Personal Package Archive (PPA) label change in Ubuntu, a common issue faced by many Ubuntu users. This step-by-step guide will provide you with detailed instructions on how to navigate this process using various methods.

Quick Answer

To explicitly accept a PPA label change in Ubuntu, you can use the apt command by running sudo apt update and sudo apt upgrade and accepting the changes when prompted. Alternatively, you can use the --allow-releaseinfo-change option with apt-get by running sudo apt-get update --allow-releaseinfo-change. Another option is to use pkcon by running pkcon refresh and pkcon update.

Introduction to PPA Label Change

A Personal Package Archive (PPA) is a software repository for uploading source packages to be built and published as an Advanced Packaging Tool (APT) repository by Launchpad. When the PPA label changes, you may encounter a message that prevents you from updating your system. This is a security measure to ensure that you are aware of the changes in the repository.

Method 1: Using apt Instead of apt-get

Starting from recent Ubuntu versions, apt is preferred over apt-get for interactive use. The apt command combines the most commonly used commands from apt-get and apt-cache, including an option to accept PPA label changes. Here’s how you can use it:

sudo apt update
sudo apt upgrade

Upon running these commands, you will be prompted with the message: “Do you want to accept these changes and continue updating from this repository? [y/N]”. Enter ‘y’ to accept the changes.

The update command is used to resynchronize the package index files from their sources. The upgrade command is used to install the newest versions of all packages currently installed on the system.

Method 2: Using --allow-releaseinfo-change with apt-get

If you prefer to use apt-get, you can use the --allow-releaseinfo-change option. This option tells apt-get to accept the change and proceed with the update. Here’s how you can use it:

sudo apt-get update --allow-releaseinfo-change

The --allow-releaseinfo-change option is a safety feature that prevents the system from automatically accepting changes in the repository. By using this option, you are explicitly allowing the changes.

Method 3: Using pkcon for Specific Cases

If you are using a specific PPA like the one mentioned in the error message, you can try using pkcon instead. The pkcon command is a part of the PackageKit system, which provides a unified high-level API for performing actions on different package management systems. Here’s how you can use it:

pkcon refresh
pkcon update

The refresh command updates the package list, and the update command upgrades all packages on the system.


In this article, we have covered three methods to explicitly accept a PPA label change in Ubuntu. Depending on your preference and system configuration, you can choose the method that suits you best. Always remember to ensure that you are aware of the changes you are accepting in your system to maintain its security and stability.

What is a PPA in Ubuntu?

A PPA (Personal Package Archive) in Ubuntu is a software repository where developers can upload packages, updates, and software to be installed on Ubuntu systems. PPAs are often used to provide newer or customized versions of software that are not available in the official Ubuntu repositories.

Why does the PPA label change?

The PPA label can change when the maintainer of the PPA updates or modifies the repository. This can include changes in the software versions, package dependencies, or other updates. The label change is a security measure to ensure that users are aware of the modifications made to the repository before updating their system.

Can I ignore the PPA label change and continue updating my system?

It is generally not recommended to ignore the PPA label change as it is a security measure to ensure the integrity of your system. However, if you are confident in the source and trust the changes made to the PPA, you can explicitly accept the label change using the methods mentioned in this article.

What is the difference between `apt` and `apt-get`?

apt and apt-get are both package management commands in Ubuntu. However, apt is the newer command that combines the most commonly used functionalities of apt-get and apt-cache. It provides a more user-friendly and intuitive interface for package management tasks. It is recommended to use apt for interactive use, but apt-get is still widely used and supported.

How do I know which PPA is causing the label change error?

The error message usually provides information about the specific PPA causing the label change error. It may include the name or URL of the PPA. You can use this information to identify the problematic PPA and take appropriate action, such as accepting the label change or disabling the PPA if necessary.

Can I revert the PPA label change after accepting it?

Once you have explicitly accepted the PPA label change and updated your system, it is not possible to revert the change. It is important to carefully review the changes before accepting them to ensure they align with your system’s requirements and security standards.

Are PPA label changes common in Ubuntu?

PPA label changes are not extremely common, but they can occur depending on the frequency of updates and modifications made by the PPA maintainers. It is always recommended to review the changes and make an informed decision before accepting them to maintain the security and stability of your system.
