The Repository 'https //download.docker.com/linux/ubuntu Kinetic Inrelease' Is Not Signed =link= «95% INSTANT»

Since Kinetic is EOL, the most stable long-term fix is to upgrade to an LTS version like or Ubuntu 24.04 (Noble) . If you must stay on your current setup, you can try pointing your Docker source to the closest LTS release (Jammy) instead. 2. Re-import the Docker GPG Key

When apt cannot find a valid signature file ( InRelease ) for a repository, it blocks the update to prevent you from installing potentially malicious or unauthenticated software. Common Causes of the "Not Signed" Error

: If your root partition or Docker's allocated disk space is full, apt may fail to download and verify the signature file, leading to a misleading "not signed" error. Since Kinetic is EOL, the most stable long-term

: Ubuntu 22.10 (Kinetic) is no longer supported. Repositories for EOL versions are often moved or archived, causing the signature check to fail.

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu jammy stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null Use code with caution. 4. Clear Cache and Check Disk Space Re-import the Docker GPG Key When apt cannot

Sometimes local corruption or full storage causes this error. Clear the apt cache and check your disk usage: Repository is not signed in docker build - Stack Overflow

Modern Ubuntu versions require the GPG key to be stored in /etc/apt/keyrings/ rather than using the deprecated apt-key command. Use the following commands: Repositories for EOL versions are often moved or

Ensure your Docker source file (usually at /etc/apt/sources.list.d/docker.list ) points to a valid and signed path. If "kinetic" continues to fail, you can temporarily try using "jammy" to see if it resolves the signature issue:
