How To Fix “APT Repository is Not Signed” Error for Wine on Ubuntu 22.04 Jammy Jellyfish

Ubuntu 19

When using Ubuntu 22.04 Jammy Jellyfish, you may encounter an error message stating “The repository ‘ jammy InRelease’ is not signed.” This issue typically arises after removing the Wine application and its associated files. The problem is likely due to a residual file in the /etc/apt/sources.list.d/ directory that was not properly removed during the uninstallation process. This article will guide you through the steps necessary to resolve this issue.

Quick Answer

To fix the "APT Repository is Not Signed" error for Wine on Ubuntu 22.04 Jammy Jellyfish, you need to navigate to the /etc/apt/sources.list.d/ directory, identify the problematic file related to the Wine repository, and remove it using the sudo rm command. Afterward, update your package lists with sudo apt update to apply the changes.

Understanding the Error

The “APT repository is not signed” error occurs when the Advanced Packaging Tool (APT) cannot verify the authenticity of a repository. This is often due to an unusual installation, uninstallation, or removal of the Wine repository. The APT tool uses a keyring to verify the signatures of packages from a repository, and if a key is missing or incorrect, it will produce this error.

Navigating to the Correct Directory

To resolve this issue, you will first need to navigate to the directory where the problematic file resides. Open a terminal and run the following command:

cd /etc/apt/sources.list.d/

This command changes the current directory to /etc/apt/sources.list.d/. The cd command stands for “change directory”.

Identifying the Problematic File

Next, you need to identify the file that corresponds to the Wine repository. This can be done by running the following command:

ls | grep wine

The ls command lists all files and directories in the current directory, while the grep command searches for a specific string in the given input. In this case, it searches for the word “wine” in the list of files and directories.

Removing the File

Once you’ve identified the problematic file (for example, wine.list or wine-builds.list), you can remove it using the following command:

sudo rm <filename>

Replace <filename> with the actual name of the file. The sudo command allows you to run commands with administrative privileges, while the rm command removes files or directories.

Updating the Package Lists

After removing the problematic file, you should update your package lists to ensure that the changes take effect. This can be done with the following command:

sudo apt update

The apt update command retrieves new lists of packages from the repositories and “updates” them to get information on the newest versions of packages and their dependencies.


By following these steps, you should be able to resolve the “APT repository is not signed” error related to the Wine repository on Ubuntu 22.04 Jammy Jellyfish. Remember, it’s important to carefully manage your repositories and remove any unnecessary or outdated ones to prevent similar issues in the future. If you encounter any other issues, the Ubuntu community and various online forums are excellent resources for finding solutions.
